Rubber-band Racer

This may be my favourite “make” from the book – as I explain in the video, I love that you can take scrap materials and make a “pull back” car, like the ones you can buy from a shop, and see exactly how it works. I’ve seen young children make these and witnessed their joy when they get theirs working – the same as mine when I first made one and, in fact, every time I’ve made one since, because it’s just so satisfying.

EXTRAS: If you liked making this car, you could try powering it using a balloon instead of a rubber band, as shown in this video I made for the Royal Institution.
