MAIN PURPOSE: Make slime in a mixing well with the add-ins beside it

A slime-making station for children. The big rounded well is for mixing and kneading and has its own lid to keep finished slime soft, and three side bays hold the activator, glitter and foam beads. It keeps the mess in one tray.

MAIN PURPOSE: Give a child in a car seat a snack and activity tray

A travel tray for long car journeys that buckles across a child's car seat. There is a big flat play area for drawing and stickers, a snack bay and a crayon trough, all with raised edges so nothing rolls into the footwell.

Rillway Pylon

MAIN PURPOSE: Carry a marble run between rail levels

A drop-shaft tower for a marble run: rails push into eight windows, four facing right and four left at staggered heights. A marble rolls down a rail, falls inside the shaft and lands on the next rail end, which carries it back the other way. Two identical pylons 180 mm apart make the zig-zag; ballast the unused base.

Rillway Rail

MAIN PURPOSE: Roll marbles between marble run pylons

The track for the Rillway run: a 230 mm open channel with filleted sides for a 16 mm marble, closed at one end and open at the other. Push the closed end into a high pylon window and the open end into a lower window on the facing pylon, so the stop catches each falling marble and the open end drops it on.

Rillway Basin

MAIN PURPOSE: Collect marbles at the end of the run

The finish line of the Rillway run: a deep filleted cup with one side wall lowered to 22 mm so the last rail rests on it, open end inside. Marbles drop in, roll round the curved floor and stay put for the next go. FINISH is engraved on the front.

Relay Stairs

MAIN PURPOSE: Carry a falling domino chain up and over

A folded ribbon staircase for domino runs: six 10 mm steps up and six down, with 20 mm treads that hold a standing domino each. A domino chain climbs over the summit and runs on down the far side, a classic chain reaction trick made neat and repeatable.

Travertine Falls

MAIN PURPOSE: Cascade water through stepped pools at bath time

A bath and paddling-pool toy that copies the terraces of Pamukkale. Pour water into the tall pool and it brims over the lowered side rims into two side pools, which spill in turn over their low front weirs into the long pool in front, just as mineral springs build their stepped basins rim by rim.

MAIN PURPOSE: Glide a printed seed wing across a 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.

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.
