Each Trial is a strategy a real species uses, turned into something you can run yourself in about ten minutes. Each card says what to do and why it helps.
What each Trial asks you to do, and what it does for you. Reading a Trial needs no account. 3.017 Trials across 2.325 species. Showing 1.981–2.040.
The Trial
Listen to five distinct everyday sounds made by someone else, then reproduce the sequence from memory using your voice or nearby objects.
Why it helps
You turn sound mimicry into one concrete, visible experience instead of an abstract idea.
10 minDifficulty 2
The Trial
Pick a houseplant with roots circling the pot or poking out of the drainage holes. Ease it out whole, loosen the root ball gently, and set it in a pot a size bigger with fresh compost around it.
Why it helps
A healthier plant with room to grow and a satisfying bit of hands-on care.
20 minDifficulty 2
The Trial
Match one thing today to one specific context in exact detail rather than to a general category approximately, and stay within it.
Why it helps
Matching a general category approximately leaves you looking slightly wrong everywhere. Matching one specific context exactly makes you invisible there.
2 minDifficulty 1
The Trial
Choose a safe ground-level sheltered nook, sit or rest there quietly for five minutes, then photograph the simple low-energy setup.
Why it helps
Five minutes in a genuinely sheltered spot, and a clear sense of which nook in your home actually works.
6 minDifficulty 1
The Trial
Assess something today entirely from a distance without approaching it, using only what can be gathered without your presence being noticed.
Why it helps
Approaching something to assess it means they know you are interested and the price changes. Assessing from distance keeps your position hidden.
2 minDifficulty 1
The Trial
Sit in a darkened room without switching on any light or screen and stay until you can make out detail you could not see at first. Name five things you can now resolve.
Why it helps
You experience proper dark adaptation, which most people never wait long enough to get.
12 minDifficulty 1
The Trial
Set a spoonful of honey or a piece of fruit where the camera can see it, then sit or lie still for fifteen minutes in the coolest room of your home in the clothes you already have on, with no blanket, heater or hot drink. When the clock reaches fifteen minutes, take the sweet refuel; stop early if you feel uncomfortably cold.
Why it helps
A proper low-power pause with a sweet reward that tastes earned.
18 minDifficulty 1
The Trial
Find a shrub, hedge or low tree that casts deep shade near the ground, preferably in a garden; in a park, frame the camera so no other people are in view. Sit or lie on a mat at ground level in that shade and stay quiet for ten minutes while a time-lapse runs.
Why it helps
Ten cool, quiet minutes out of the glare and bustle.
12 minDifficulty 1
The Trial
Make the place you recover from one effort today both cheap and out of sight, and strip out whatever upkeep that place currently demands of you.
Why it helps
A recovery place that needs looking after is another job, and you stop using it. One that costs nothing and nobody sees is the only kind you will actually go to.
2 minDifficulty 1
The Trial
At dusk, dress in clothes close in colour and tone to your seat or the background behind it, settle on a garden bench, step or chair by a window, and set your phone on a time-lapse facing you and the sky. Stay still with your eyes half-closed for ten minutes.
Why it helps
Ten quiet minutes of real stillness and a front-row seat for the day ending.
12 minDifficulty 1
The Trial
Pick one backdrop, such as a patterned sofa, a hedge, a pile of cushions or a bookcase, and put on clothes or a blanket in its colours and pattern. Settle low against it and rest without moving for ten minutes, with a phone timelapse set up a few metres away.
Why it helps
A playful, genuinely restful ten minutes of doing nothing well.
12 minDifficulty 1
The Trial
Find two cheap savings available to you today, sharing something and delaying a start, and take both. Do not try to make up the difference by working harder anywhere.
Why it helps
Meeting a shortfall by working harder is the most expensive option and the first one you reach for. Two cheap savings stacked usually cover it and cost you nothing you will miss.
2 minDifficulty 3
The Trial
Lie on a sofa, bed or floor and cover yourself with light cushions and a blanket up to your chin so only your face shows. Rest there, still, for ten minutes.
Why it helps
Ten cosy, sheltered minutes that calm the nervous system.
12 minDifficulty 1
The Trial
Find the window today when the conditions for rest actually exist, quiet, nobody needing you, nothing running, and rest in that window rather than at your usual time.
Why it helps
Resting at your usual time when conditions are wrong means you are interrupted and get nothing from it. Taking the window that is actually quiet is real rest.
2 minDifficulty 1
The Trial
Choose one everyday item whose protective surface needs care and clean, dry, polish or restore that layer. Stop once the protective surface is working again.
Why it helps
You get a concrete, memorable result while practising element switch as a real human action.
10 minDifficulty 2
The Trial
Before starting, press at least twelve even ridges and valleys radiating from the centre of a round tray of sand or salt. While you look away, a consenting helper wipes one quarter flat with the side of a hand; on go you rebuild its ridges and valleys by finger to match the opposite quarter within twenty seconds, and the helper does this three times, choosing a different quarter each time.
Why it helps
A tense little repair race that trains fast, accurate hands.
5 minDifficulty 4
The Trial
Restart one abandoned project today from exactly where it stopped, without redoing or reviewing what was already finished. Spend fifteen minutes adding the next piece only.
Why it helps
Restarting a stalled project by reviewing everything already done means you never reach new work and abandon it again. Resuming at the stopping point gets you moving immediately.
2 minDifficulty 2
The Trial
On a warm day, find the lowest, deepest shade outdoors, such as under a shrub, hedge or low garden table, and leave a thermometer for three minutes in the open sun and then three minutes inside the refuge, reading it each time. Settle low in the refuge with water to hand and stay still for ten minutes.
Why it helps
A cooler, calmer break on a hot day, and a lasting sense of where the deepest shade really is.
20 minDifficulty 1
Amazonian Manatee · RivergentleThe Trial
Name the lean stretch you are in. Withdraw today to the smallest, deepest arrangement you can hold, stop seeking new input entirely, and live on what you stored.
Why it helps
Trying to keep operating at full size through a lean stretch burns the reserves you need to be there when it ends. Withdrawing to the deep water is how you are still alive when the river rises.
2 minDifficulty 1
The Trial
From a stable seated position, use a long safe reach tool to collect five lightweight objects placed below arm level.
Why it helps
You turn contrast into one concrete, visible experience instead of an abstract idea.
10 minDifficulty 2
The Trial
Find one item that has rolled or slipped under a sofa, bed or cupboard, or slide a sock there. Without kneeling to reach in by hand or moving the furniture, choose the longest tool in the house that fits the gap, such as a broom handle or a long ruler, and draw the item out into the open.
Why it helps
You have something about you that seems odd or too much. Put to the one job it suits, it stops being awkward and starts doing work that others around you cannot do as easily.
2 minDifficulty 2
The Trial
Fill a washing-up bowl with water and place two mugs or a few large stones on the bottom. Drop three coins in so that at least one lands under or behind an object. Find all three using one hand under the surface, without tipping out any water.
Why it helps
Waiting for answers, people or chances to come to you can take forever. Going into the place where they already are, and searching it properly, gets you what you need faster.
2 minDifficulty 2
The Trial
Loop one arm securely over the back of a sturdy chair while standing beside it, and use only the free hand to retrieve three lightweight objects within easy reach.
Why it helps
You turn curiosity into one concrete experience with a visible finish.
10 minDifficulty 2
The Trial
Keep one input consistent today rather than varying it, returning to the same sources so the process handling it stays tuned.
Why it helps
Varying your inputs means the process handling them never settles and output stays poor. Keeping them consistent makes the same process far more efficient.
2 minDifficulty 1
The Trial
Work a slow circuit today of places that have produced for you before, rather than searching anywhere new.
Why it helps
Searching new ground at speed costs you everything and finds little. A slow circuit of places that produced before pays almost every time.
2 minDifficulty 1
The Trial
When activated, fold a sheet of paper so two large drawn eye circles are hidden, then open it toward the camera in one motion to reveal both at once.
Why it helps
You turn revelation into one concrete experience with a visible finish.
5 minDifficulty 3
The Trial
Enter one borrowed space today oriented so your defence faces the entrance, rather than facing inward and being approached from behind.
Why it helps
Facing inward in a borrowed space means whatever follows you in arrives behind you. Reversing in costs nothing and the entrance is covered.
2 minDifficulty 3
The Trial
Make the warning before a response you would rather not use explicit and unmissable today, and state what the response will cost you as well.
Why it helps
Warnings that hide your own cost sound like bluffs and get tested. Saying what it will cost you too is what makes people believe it.
1 minDifficulty 4
The Trial
Reverse one process today by changing the direction of its internal sequence rather than turning the whole thing around.
Why it helps
Turning a whole process around to reverse it means you dismantle and rebuild it. Reversing the internal sequence takes seconds and nothing moves.
2 minDifficulty 2
The Trial
Attach yourself today to a person or process that will eventually produce what you want, and wait rather than pursuing the thing itself.
Why it helps
Chasing the thing itself means arriving after it exists and competing. Attaching early to whoever makes it means you are already inside when it appears.
2 minDifficulty 1
The Trial
Tape a one-metre square on the floor about three metres from a caged desk fan set on low and aimed across the room at it, then release a small, lightly inflated balloon just in front of the fan. Let the draft do the travelling and steer it with at most five light fingertip taps from above or the side until it comes to rest inside the square; if it drifts out or you run out of taps, walk it back and start a fresh run.
Why it helps
A calm, absorbing few minutes that shows how little effort it takes when you work with a flow instead of against it.
10 minDifficulty 2
The Trial
Work with one unstable situation today by moving with its changes rather than stabilising it, and abandon the effort you were making to steady it.
Why it helps
Trying to steady a situation that will not hold still spends everything you have on the stabilising. Moving with it instead leaves you free to actually get something done.
2 minDifficulty 2
The Trial
Make one journey today as cheap as you can: take the route that asks least of you, carry less, and arrive with the energy you would normally have spent still in hand. Spend it on what you went for.
Why it helps
Spending the same effort on travel as on the thing that matters leaves you with nothing at the moment of action. Cheap transit keeps your energy where it counts.
2 minDifficulty 2
The Trial
Name one thing you have been pushing uphill by yourself. Find the current already heading that way today, an existing meeting, deadline or project, attach your thing to it, and only do the part nothing can carry.
Why it helps
Pushing something uphill alone when a current is already heading that way wastes most of your effort on movement you could have had free. Attaching it leaves you only the climb nothing else can do.
1 minDifficulty 3
The Trial
Find something already disrupting your area today, a reorganisation, a new system, an argument, and position yourself to take what it flushes out.
Why it helps
Searching your own area while a disruption is happening elsewhere in it means you miss everything it shakes loose. Positioning for it costs you nothing.
2 minDifficulty 3
The Trial
Put a snack in a bowl and rig a loose string round it tied to a tin holding a few keys or bottle caps, so any reach for the bowl makes the tin clatter. Invite a consenting partner to try to take the snack and let the alarm go off.
Why it helps
A fun bit of home engineering, and a reminder that a clear signal can protect without hurting.
12 minDifficulty 2
The Trial
Tuck a flat piece of cardboard or a folded umbrella into the back of a backpack or waistband so it arches over your head and shoulders. Sit in an open, sunny spot and shell a bowl of peas or pod beans with both hands, keeping your head and hands in the shade you carry.
Why it helps
A clever bit of kit that makes sunny outdoor jobs comfortable.
15 minDifficulty 2
The Trial
Work out today which capability you technically still have but cannot actually afford to use, and plan as if you did not have it.
Why it helps
Counting on a capability you cannot afford to use means your plan fails at the moment you need it. Planning without it is more honest and more robust.
2 minDifficulty 1
The Trial
Pick one area where you have been trying to stay flexible and keep getting pulled around. Fix something rigidly today, a policy, a rate or a schedule, and accept the slowness it costs you.
Why it helps
Staying flexible in an area where people keep pushing means you spend every week renegotiating the same thing. One rigid rule costs you some speed and ends the renegotiation entirely.
2 minDifficulty 1
The Trial
Remove one option or degree of flexibility today that is costing you efficiency, and lock the thing into a single rigid form.
Why it helps
Keeping options open on everything means every one of them costs you a little efficiency all day. Locking one into a rigid form is where the depth comes from.
2 minDifficulty 2
The Trial
Collect pinecones in a colour close to your potting soil and set them upright around the surface of one plant pot, points up, so there is no bare patch big enough for a paw to dig in.
Why it helps
A calm, natural fix that stops pets and squirrels digging up your plants.
10 minDifficulty 1
The Trial
Use no more than one measured cup of water to rinse salt or seasoning from one washable food-safe item or utensil, catching the used water in a bowl.
Why it helps
You turn mud concealment into one concrete experience with a visible finish.
10 minDifficulty 2
The Trial
Float a ping-pong ball in the middle of a filled sink or basin and hold a cup on its side at one edge, with its opening half above and half below the waterline. Make one push of water with a flat hand at the opposite side so the ball is carried away from it into the cup.
Why it helps
A calm little physics game that feels uncanny once the ball starts arriving on cue.
10 minDifficulty 2
The Trial
Lay a rope or long scarf straight on a smooth floor and stand a paper cup just past the far end. Hold your end at floor level and send one smooth side-to-side wave down its length to tip the cup; reset and repeat until you have three topples.
Why it helps
A playful physics puzzle about how a wave carries energy.
10 minDifficulty 2
The Trial
Stand three or more people side by side facing the same way, each watching only the person on their right. The end person makes a quarter turn whenever they choose, and each person turns as soon as their neighbour does, until five turns have rippled all the way down the line.
Why it helps
A quick group game that shows how fast a crowd can move without anyone in charge.
10 minDifficulty 2
The Trial
Learn the specific signature of one thing you are waiting for today, so you can tell it from the background rather than reacting to everything.
Why it helps
Reacting to everything that disturbs the surface means a day of false alarms. Knowing the one signature means the background stops costing you anything.
2 minDifficulty 2
The Trial
Take one breath and produce a single continuous call that begins at the lowest note you can make and rises without a break to the highest you can reach. Do it once, at full commitment.
Why it helps
Ten seconds that are genuinely funny to watch back, and a range you did not know you had.
2 minDifficulty 2
The Trial
Match the rhythm of a moving environment today rather than holding still in it, moving with it at its own pace.
Why it helps
Holding perfectly still in a moving environment makes you the only static thing in it. Matching its rhythm is what actually makes you disappear.
2 minDifficulty 1
The Trial
Deliberately keep changing your angle on something today rather than holding a steady view, and note what the changing angle reveals.
Why it helps
A steady view of something shows you the same thing all day. Changing the angle repeatedly is what surfaces what the steady view was hiding.
2 minDifficulty 2
The Trial
Take one situation where you have been conspicuously inactive. Add one small ordinary movement today, a routine contribution or a brief appearance, so the quiet stops being the notable thing.
Why it helps
Going completely quiet in a place where everything else moves makes your absence the most visible thing there. One small ordinary movement lets you stay out of it without anyone wondering why.
2 minDifficulty 1
The Trial
Pick one situation today where you have been rigidly holding a position. Move with it instead for one exchange, going where it goes, and take your one real action only when it comes within reach.
Why it helps
Holding a fixed position makes you the obvious thing in the room and gets you worked around. Moving with it keeps you in play until the moment you actually need something arrives.
2 minDifficulty 1
The Trial
Let one thing move with whatever is already moving around it today instead of holding it fixed, and release whatever you are using to keep it rigid.
Why it helps
Holding something rigid while everything around it shifts is what makes it stand out, and it costs you the effort of holding. Letting it move with the rest hides it for free.
2 minDifficulty 1
The Trial
Enter one busy shared space today and spend a few minutes deliberately matching its pace and rhythm rather than standing out or withdrawing, then do the small thing you came to do from inside that rhythm.
Why it helps
Standing out or hiding both cost you the room, because people read either as something to manage. Matching the rhythm first lets you do the actual thing without anyone having to deal with you.
1 minDifficulty 3
The Trial
Take one sheet of paper and one small object, such as a coin or a wrapped sweet. Fold and roll the sheet around the object into a tight parcel, tucking the loose end into the folds so it stays closed. Use no tape, glue, staples or string. Then drop the parcel from table height onto the floor and pick it up.
Why it helps
You reach for extra fixes when the material you already have could do the job if shaped properly. Getting the structure right first saves you buying, sticking and redoing things later.
2 minDifficulty 2
The Trial
Roll paper or thin cardboard into a tight tube and tape it. Align the tube along a broom handle, chair leg, or plant stake. Place a small token inside, keep the tube closed for ten minutes, and only open once briefly to check before resealing.
Why it helps
You practice staying covered along a line instead of lingering in the open.
12 minDifficulty 1
The Trial
Pair one strong action today with a second that removes the need for all the follow-up work, rather than planning the follow-up.
Why it helps
A strong action with a long follow-up means you are still working days later. A second action that removes the follow-up ends it on the day.
1 minDifficulty 4
The Trial
Tear two matching frog shapes from paper towel and dampen both with the same spoonful of water each. Roll one loosely inside three or four large fresh leaves picked from your own plants, or outer cabbage leaves, and lay the roll beside the open frog in direct sun or a breeze on a sill; leave both untouched for twenty minutes, then unroll the leaves and throw them away.
Why it helps
A slow, quiet little experiment that shows how much moisture a roll of living leaves can hold in.
20 minDifficulty 1
The Trial
Take a large lettuce or cabbage leaf and fill it with one shoot, such as asparagus, pea shoots or bean sprouts, one fruit, such as apple or tomato, and one root, such as grated carrot or radish. Roll it up and eat it sitting upright, holding it in both hands with no plate or cutlery.
Why it helps
A fresh, crunchy snack that gets four kinds of plant into one bite.
12 minDifficulty 2
The Trial
Take a large leaf of lettuce, cabbage or chard and leave it out for an hour or dip it briefly in warm water so it softens. Lay three small beads or dried peas at one end, roll the leaf tightly around them and tuck the loose tip and edges in so the roll closes itself.
Why it helps
A fiddly, calming bit of folding that uses up a limp leaf of lettuce.
10 minDifficulty 2
The Trial
Set out six numbered cups as parts of a city and roll a die, dropping one bead into the cup matching the number for each roll while keeping a tally mark per roll on paper. Stop the moment any cup holds four beads and circle that cup's number with the total roll count.
Why it helps
A hands-on feel for how random arrivals pile up into a threshold, the same maths behind wild parrot flocks in cities.
10 minDifficulty 2
