To promote the UK’s National STEM Centre, science teacher Alom Shaha shows how to build a device which demonstrates the principles of wave physics using some duct tape, kebab sticks and Jelly Babies:

The Wave Machine is a fun and useful tool for the science classroom as it can be used to demonstrate transverse wave motion and is a great way of demonstrating how light waves change when moving through different media such as glass and air. If you like this demonstration video please share your thoughts on the National STEM Centre webpage.

Neat. Plus, you know, it requires delicious jelly babies! The Doctor would be so proud:
