This is a game I first heard about from my friend, the brilliant science educator Sai Pathmanathan, who saw some children playing a version of it at one of the science clubs she runs. I have adapted the game and come up with some rules, which you can download by clicking the link below. It’s incredibly simple to make, and fun to play with children or adults. You could make the game extra special as a gift by selecting items which perhaps hold some special meaning for the person you make it for.

The video above was one of a series made by myself and a whole bunch of other “makers” as part of “A Month of Making”, a campaign I helped launch with the people behind the Queen Elizabeth Prize for Engineering to encourage people to make their own Christmas presents this year. The campaign features “makes” from Sai and a diverse range of other incredibly talented people, showing how to make everything from a hot chocolate bomb to an infinity photo cube to a delightful “wobbler” which I loved making for my daughters.
