Where to start for a physics demo?

Physics is all around us, but sometimes its hard to notice because we take it for granted! Are you having some trouble thinking of what physics to film for the Wonders of Physics Video Competition? Well you’ve come to the right place!

Below in each physics topic, we have some questions that could kickstart your curiosity, materials I’m your home that could spark your science imagination, some inexpensive products that could lead to great demonstrations, and even a few simple experiments that you could start filming!

We hope this will help you get started on your video, and of course, we encourage you think of even more physics to film!
