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.

Eumenes

MAIN PURPOSE: Hold dip pen ink in a stable narrow-necked pot

An inkwell shaped like the nest of a potter wasp, the tiny clay pot with a narrow neck and flared lip that wasps build on twigs. The squat, heavy body will not tip, the narrow neck slows evaporation and the flared lip wipes the nib.

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.

Vespiary

MAIN PURPOSE: Hang a ball of twine and pull it from below

A hanging dispenser for butcher’s or garden twine, after a hornet nest, whose layered paper envelope opens only underneath. The ball sits inside, the end feeds out of the single hole in the base, and the ring on the screw cap hangs it from a hook, so the string is always to hand and never rolls away.

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.

Odonata

MAIN PURPOSE: Work on a laptop or sketch on the sofa

A lap board for a laptop or sketchbook, stiffened like a dragonfly wing. Wing veins run densest along the leading edge and branch into cells across a thin membrane; here a thin skin rides on ribs laid out the same way, so a 250 mm board stays flat on your knees and weighs little. Vents in the cells let a laptop breathe.

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.

Pod of Five

MAIN PURPOSE: Give five truffles in a pea pod box

A gift box for five chocolate truffles shaped like a pea pod. Five cells line up along the curved pod, one per truffle, and the snug lid closes it like a pod not yet split. Fill it with truffles, sugared almonds or macarons as a small present.

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.
