Made this in the kitchen this morning. Hope you like it Mixing Ice and Salt in Infrared youtu.be/rhv5IEKIObI

Action of coloured filters

Another lunchtime spent on making a short today: The jumping / floating ring demonstration with infrared camera youtube.com/shorts/KZTIQ3w…

Demonstrating how fuses and the earth wire work This is my cheap, large and easy to make version of a demonstration originally described by Mark Harrison in Physics Education Journal youtu.be/bSoFhj3SRVY

Traditional school holiday improbable circular motion video completed: youtube.com/shorts/QJvcnFW…

Much improved video of balanced can circular motion: Surely a can balanced on its edge can’t do vertical circular motion! youtu.be/OC9PlwYR1ws Still find it hard to believe it works

Whenever questions about explaining refraction with wavefronts come up on AQA GCSE physics/ combined science they are not well answered. Zooming in on the PhET bending light simulation really helps to explain it to students. youtu.be/E_Qt9zQdMEQ Thanks to PhET Sims

I was pleased that I managed to calculate the speed of the metal plate with the doppler effect: youtu.be/tCmhUw2uKlo

Thought it would be fun to project a spectrum onto glow in the dark vinyl. Here is the result: youtu.be/gIvT2Nx2dB8

If you enjoyed the waves ideas I posted yesterday, the. a reminder about the forces and motion ones I shared 6 months ago.

I think mounting the magnet on a glass rod gets the best out of magnetic field chips youtu.be/pPDsVYkGyM8

A great thank you present from some of my A-level students. As it doesn’t have a case you can see how it works. youtu.be/vmkKEfvzeFI

Gas discharge tubes with plasma globe. Thanks to Arbor Scientific for the idea. Viewed through 1000 lines per mm diffraction grating film. youtu.be/AjuKXOFSdjY

I made a video about electron diffraction which features a new demonstration which uses three crossed diffraction gratings, a violet laser & glow in the dark film to show & explain simply why the electron diffraction produces rings at 3 mins 30. youtu.be/XAtYh0dBWaU
