MAIN PURPOSE: Show that the spectrum colours mix to white

Colour the seven ribbed sectors red, orange, yellow, green, blue, indigo and violet, push a pencil through the centre and spin it like a top: the colours blend into a pale grey white, Newton's proof that white light is all the colours together.

Aquarium stem-plant anchor ring

MAIN PURPOSE: Hold stem-plant cuttings down in the gravel

Push a bunch of stem-plant cuttings through the centre hole and bury the flower-shaped ring in the gravel: the cuttings stay planted while they root through the side holes, instead of floating up every time the fish dig or you vacuum.

Aquarium pest snail trap

MAIN PURPOSE: Remove pest snails from a tank without chemicals

Put a slice of blanched courgette inside, close the lid and leave it on the gravel overnight: pest snails crawl in through the low slots to feed, and in the morning you lift the whole trap out with them inside. No chemicals that harm shrimp.

Reptile humid hide rock

MAIN PURPOSE: Give a reptile a humid hide for shedding

A rock-shaped shell with a 50 mm entrance in its crown: pack it with damp sphagnum moss and geckos and snakes get the humid retreat they need to shed cleanly. It has no floor, so you lift the whole rock to mist and check the moss. Print it as shown, then turn it over so the floor becomes the top.

Filter intake baby-shrimp guard

MAIN PURPOSE: Stop baby shrimp being sucked into a filter

Slide the slotted sleeve over a 16 mm filter intake: the fine slots on all four sides still let water through freely, but baby shrimp and fry can no longer be sucked into the filter. Cleans with a shake under the tap.

Dog nail scratch board with treat box

MAIN PURPOSE: Let a dog file its own nails

Glue a sheet of coarse sandpaper into the tray and hide a treat in the lidded box at the end: the dog learns to dig at the board for it and files its own nails down, with none of the clipping stress for either of you.

Cherry tomato halving trays

MAIN PURPOSE: Halve a batch of cherry tomatoes in one cut

Fill one tray with 16 cherry tomatoes or grapes, lay the second tray upside down on top and press it flat with your palm: the shallow 7 mm cells hold every tomato at the same height, so one pass of a long serrated knife through the gap halves the lot without a single one rolling away. Print two.

Corn cob stripping bowl

MAIN PURPOSE: Cut kernels off a corn cob without the mess

Stand the cob on the 28 mm hub and run a knife down it: the hub holds the cob upright and steady, the four spokes brace it and split the bowl into quarters, and the kernels land in the 170 mm bowl instead of across the worktop. The same hub steadies a cob for buttering.

Rice cooking water dipstick

MAIN PURPOSE: Add exactly the right water to rice

Level the rinsed rice in the pan, stand the foot on the surface and pour water until it reaches the right notch: 15 mm for jasmine and sushi rice, 20 mm for long grain, 25 mm for brown. Measuring the depth above the rice works for any pan and any amount, which cup ratios never do.

Garlic peeling shaker

MAIN PURPOSE: Peel a whole bulb of garlic by shaking

Drop in a whole bulb of cloves, push on the friction lid and shake hard for 20 seconds: six low ribs knock the cloves against each other and the wall, and the papery skins come off without crushing or smelly fingers. Tip out the cloves, blow out the skins.
