Summary

In this programme, David Richardson from the Institute of Physics is invited to the Twilight Club at St. James' Catholic High School in London to demonstrate his physics experiments to science staff.

Alongside these demonstrations, we see one teacher testing the experiments out with his Year 7 pupils. Almost all of the experiments are created using everyday objects. They include:

  • Lemonade bottles filled with water containing tomato ketchup sachets which act like Cartesian divers
  • Marshmallows in a wine bottle expanding while the air is pumped out of the bottle to demonstrate the effect of air pressure
  • Surprising ways of showing turning moments
  • The effects of gravity
  • Floating and sinking
