Stuck at home? Why not do some science? Today, with the help of Penny the Cat, I demonstrate how to make a homemade magnifying glass with things you probably have around the house.

I’ll also explain how it works – through the science of vision and light, and the power of lenses. Come for the science, stay for the awkward sound effects and the time Penny knocks stuff off the couch.
