Preview of Elastic hair-tie guitar capo
By Krypto
Complexity
Simple
MAIN PURPOSE: Make a spare capo from a hair tie
Press the padded bar across the frets and loop a hair tie from one end notch, under the neck, to the other: a capo that weighs nothing, fits any neck width up to 56 mm and costs pennies, ideal as a spare in every gig bag.

Preview of Kamal latitude finder
By Krypto
Complexity
Simple
MAIN PURPOSE: Measure latitude from the Pole Star
The card Arab navigators used to find latitude: hold the knotted cord in your teeth, push the card out until the bottom edge sits on the horizon and the top edge touches the Pole Star. A knot for each place you know becomes a latitude scale.

Preview of Litre cube
By Krypto
Complexity
Simple
MAIN PURPOSE: Show that a litre is a 10 cm cube
A hollow cube exactly 10 cm inside in every direction: fill it with water from a measuring jug and children see that one litre and 1000 cubic centimetres are the same thing, then weigh it and meet the kilogram too.

Preview of Leeuwenhoek ball-lens microscope
By Krypto
Complexity
Simple
MAIN PURPOSE: See cells with a single glass bead lens
A slide-sized plate with seats for a 2 mm and a 3 mm glass bead, the trick Antonie van Leeuwenhoek used in the 1670s: tape a specimen to the back, hold the bead to your eye and see cells at up to 150 times, with a lens that cost almost nothing.

Preview of Eureka overflow can for rock density
By Krypto
Complexity
Simple
MAIN PURPOSE: Measure rock volume and density by displacement
Fill the can until water runs from the spout, lower in a rock on a thread and catch the overflow in a measuring cylinder: that is the rock volume. Divide its weight by it and pupils can tell granite from basalt from a lump of pyrite by density alone.

Preview of Newton colour wheel spinner
By Krypto
Complexity
Simple
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.

Preview of Reptile humid hide rock
By Krypto
Complexity
Simple
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.

Preview of Stackable flying altitude risers
By Krypto
Complexity
Simple (set)
MAIN PURPOSE: Show how high a flying miniature is
A 25 mm miniature base drops into the top of a riser and each riser nests into the next by its grip foot: every level lifts the model 12 mm and stands for 10 ft of altitude, so flying creatures show their height at a glance and range checks become simple counting instead of notes on paper.

Preview of Player-board edge track slider
By Krypto
Complexity
Simple
MAIN PURPOSE: Mark track positions that cannot be knocked off
Clips over the 2 mm edge of a player board and slides along it, with a pointed arm that reaches over the printed score or resource track: unlike a loose cube, the marker cannot be knocked off or nudged one space by an elbow, and the spring jaw holds it on the right square.

Preview of Shape-coded cube caps for colour-blind players
By Krypto
Complexity
Simple (set)
MAIN PURPOSE: Make player pieces readable without colour
A thin hexagonal shell drops over a standard 8 mm wooden cube, so one player's cubes are recognisable by shape as well as colour. Print the other players' sets in the triangle, heart, gear or star base types and nobody has to ask which red is which again. Print it as shown, then turn it over so the floor becomes the top.
