How Can Jelly Babies Make Waves?

A wave machine is a great way to demonstrate how light waves change when moving through different media such as glass and air.

This fun demonstration of transverse waves by the National STEM Centre shows how to make a wave machine from jelly babies.

It has also been done with marshmallows instead of jelly babies. Why not build your own wave machine, experiment to find out which sweets work best … and then eat them!
