| Abstract |
Investigate what to do if your Van der Graaf generator doesn't work in front of an expectant year 11 group and what happens if you put a light bulb in a microwave oven and then turn it on. In this programme, David Richardson from the Institute of Physics does more experiments for the staff at St. James Catholic High School in London. Head of Biology Wendy Butler has always been afraid of using the Van der Graaf Generator. David shows her how to use it dramatically and safely and she then uses his advice to demonstrate the Generator to her Year 11 group for the first time. Wendy is keen to impress her students and also tries out other Van der Graaf experiments that she has researched for herself.David does some other striking experiments, including partially immersing a light bulb in a beaker of water and placing it in a microwave oven. The bulb lights up and David explains why. |

Discover how to make marshmallows treble in size, hold an upturned glass of water over your head without getting wet and make a big box balance with most of it overhanging on a bench. 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 some of his experiments to science staff the majority of which are non-physics specialists. Almost all of the experiments are created using everyday objects, including lemonade bottles filled with water containing tomato ketchup sachets acting like Cartesian Divers, and marshmallows in a wine bottle expanding while the air is pumped out of the bottle to demonstrate the effect of air pressure. Other experiments include surprising ways of showing turning moments, the effects of gravity, plus floating and sinking. Alongside these demonstrations, we see one teacher trying the experiments out with his Year 7 pupils. |
