Preview of Rillway Rail
By Krypto
Complexity
Simple (set)
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.

Complexity
Simple
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.

Preview of Relay Stairs
By Krypto
Complexity
Simple
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.

Preview of Travertine Falls
By Krypto
Complexity
Advanced
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.

By Krypto
Complexity
Simple
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.

Preview of Caddis
By Krypto
Complexity
Medium
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.

Preview of Awnwalker
By Krypto
Complexity
Simple
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.

Preview of Shoe-lacing trainer board
By Krypto
Complexity
Medium
MAIN PURPOSE: Teach children to lace and tie shoes
A flat shoe with six eyelets in two rows: children practise criss-cross lacing and the bunny-ears bow on the table, with both hands free and the laces facing them, instead of bending over a real shoe on a moving foot. Use a bright two-colour lace so left and right are easy to follow.

Preview of Boba-straw construction cube hubs
By Krypto
Complexity
Medium
MAIN PURPOSE: Build large frames from drinking straws
Closed 32 mm cubes with a 12.5 mm socket on all six faces: push in 12 mm bubble-tea straws, cut to any length, and build frames, towers and domes that are light, cheap and big enough to sit inside. Straws snip with scissors, so children design their own lengths.

Preview of Cup-and-ball catch game
By Krypto
Complexity
Medium
MAIN PURPOSE: Practise hand-eye coordination with a catch game
The old bilboquet: swing a ball on a cord up into the 59 mm cup. The cord runs up the hollow handle and out through the cup floor, so the knot sits safely inside the handle end and nothing snags on a swing. A table-tennis ball keeps it gentle indoors.
