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.

Preview of Tap-powered paddle wheel
By Krypto
Complexity
Simple
MAIN PURPOSE: Explore water power under a running tap
Eight paddles round a hub: push a chopstick through the centre, hold both ends under a running tap or a jug and the wheel spins, faster as the stream grows. Children discover cause and effect, then lift it higher or lower to see how the drop changes the speed.

Preview of Cardboard den corner clips
By Krypto
Complexity
Simple (set)
MAIN PURPOSE: Join cardboard sheets into dens and buildings
An L-shaped clip with a 4.5 mm slot down each arm: push two sheets of corrugated cardboard into it at right angles and they stand on their own, so a few delivery boxes become a den, a shop or a castle with no tape. Clips pull off and the cardboard stays reusable.

Preview of Twist-lid busy board
By Krypto
Complexity
Multi-part assembly
MAIN PURPOSE: Help toddlers practise twisting lids open
Three 50 mm jars stand on a board, each with a different screw lid: a knob, a bar and a ring. Toddlers learn the twisting motion with three grips, and hiding a small toy in one jar turns it into a game. Every part is big enough to be no choking risk.

Preview of Slotted building discs
By Krypto
Complexity
Simple
MAIN PURPOSE: Build open-ended models from one interlocking part
40 mm discs with eight radial slots: any two push together at any slot, in line or crossed, so a pile of identical pieces becomes spheres, chains, animals and towers. One shape, endless joints; print dozens in mixed colours from leftover filament.

Preview of Finger-tracing letter tile
By Krypto
Complexity
Simple
MAIN PURPOSE: Teach letter shapes by tracing them with a finger
A tile with one large letter engraved 2 mm deep: the groove guides a fingertip along the correct path, so pre-writers learn the shape by touch before they hold a pencil, the Montessori way. Change the letter for each tile of the set.

Preview of Balloon-powered car chassis
By Krypto
Complexity
Medium
MAIN PURPOSE: Build a balloon-jet racing car
A light open chassis with axle holes for two drinking straws and a nozzle hole in the back: add skewers, four bottle-top wheels and a balloon taped to a straw, and the car races across the floor on its own jet. Children can tune it by changing the nozzle or the wheels.

Preview of Leaky stacking pour cups
By Krypto
Complexity
Simple (set)
MAIN PURPOSE: Explore flow and draining in bath play
Bath cups that leak on purpose: a heart, a large hole and a pinhole in the floor pour three different streams, so toddlers see that a bigger hole empties faster. The grip foot lets the cups stack into a tower that drains from cup to cup.
