How to build a homemade Rubik’s cube to help a mathematical school project

Some years ago, David, an elementary School teacher wrote me asking if I can help them designing a 2×2 Rubik’s cube for children.

Rubik  cube project 2x2 for kids

They want a mathematical project for kids based on Rubik cube. Fastly I answered with some links to learn to build 2×2 and 3×3 Rubik’s cube with dices and magnets. The are really cool hacks. But David needs something easier and cheaper. They came with simple premises.

  • Children of 10 years must be able to build it, so we forget about elaborate and dangerous tools and processes

How to make Galalith or plastic stone. A bioplastic from milk

This is an easy experiment, awesome for kids. Making it we will can explain our children what bioplastic are and introduce them into a chemistry world. Even in historical facts.

Galalith or Milkstone has an interesting history behind it. It was use to produce gemestone realistic imitations.

Other Galalith names: Milkstone, Erinoid (United Kingdom), aladdinite (USA), Casolith (Netherlands) and lactoloid (Japan).
