MAIN PURPOSE: Keep keys afloat when they fall in water

A floating key fob after bladderwrack, the seaweed that holds its fronds up to the light with gas-filled bladders. The sealed 34 mm capsule displaces about 58 ml, enough to keep a car key and a couple of others on the surface if they go over the side. The ring handle takes the key ring.

Termitary

MAIN PURPOSE: Fruit a mushroom grow kit with passive airflow

A fruiting chamber for mushroom grow kits, ventilated like a termite mound. Termites farm fungus inside mounds that breathe by the stack effect; here low slots on the front take in fresh air and high slots at the back let the warm moist air out, so oyster mushrooms get humidity without stale air.

Samara Drop

MAIN PURPOSE: Show autorotation with a printed maple seed

A flying maple key. Press an M4 nut into the seed pocket, drop it from a stair or balcony and it autorotates like a sycamore seed, spinning down slowly on its single wing. Bend the trailing edge slightly to change its spin.

Alsomitra

MAIN PURPOSE: Glide a printed seed wing across a room

A hand glider after the seed of the Javan cucumber, the swept crescent wing that inspired early tailless aircraft. Press an M4 nut into the nose pocket for balance, then launch it gently level from a height and it glides in long, slow swings across the room.

Caddis

MAIN PURPOSE: Decorate a pen pot with found treasures

A pencil pot children finish themselves, after the caddisfly larva that builds its case from pebbles, sand and shell. The wall is covered in shallow round sockets: glue in beach pebbles, sea glass, beads or shells found on walks and the pot becomes a record of where they have been.

Burdock Rake

MAIN PURPOSE: Lift pet hair from sofas, car seats and beds

A pet hair remover that works like a burr. Burdock hooks catch fur and let go one way only; the edge of this rake is a row of small raked hooks, so a pull across the sofa gathers hair into a roll and a push releases it. Hang it by the hole in the handle.

Strobilus

MAIN PURPOSE: Read the humidity from a real pine cone

A pine cone hygrometer. Cone scales open as air dries and close when it is damp, a movement with no power or electronics. Sit a real cone in the cup against the back board and read how far its scales reach: past the WET marks, past the DRY marks, or in between.

Tendril

MAIN PURPOSE: Gather plant stems round a cane without tying

A support for floppy stems that coils like a tendril. Slide the hub down a garden cane to the right height, then feed the stems of peonies, tomatoes or tall herbs into the open end of the spiral and slide them round into its turns. Nothing needs tying, and each stem keeps its own channel.

MAIN PURPOSE: Play a pair of seed pod castanets

Castanets from a seed pod. Jacaranda pods are round woody shells that children clack together; print two of these cupped valves, tie them through the stalk holes with cord so the rims face each other, loop the cord over your thumb and snap them with your fingers.

Awnwalker

MAIN PURPOSE: Make a vibration-powered walking toy

A bristlebot that walks like a grass seed. A wild oat awn has stiff backward barbs, so every shake ratchets the seed forward; this body stands on eight raked legs, and a coin vibration motor with a CR2032 in its hollow back makes it scurry across the table.
