Light is reflected off a flexible shiny surface fixed to the end of a plastic tube. When one speaks into the tubes sound vibrations pass down the tube and make the surface vibrate. The reflected light is therefore sent off from the surface in a con....

When two different types of conductors are pushed into a potato chemical reactions take place charging them up - we have a simple electrochemical cell. A potato, zinc screw and carbon rod produce about 1V. We experiment joining a few of these cells u....

This is a simple yet effective demonstration of electricity generation. 500 turns of wire are wound onto a 35mm film can and the two ends are attached to an LED light. A strong magnet is placed in the can and the lid fixed back in place. The generato....

When two different metals are placed in a salt solution (an electrolyte) the chemistry produces a voltage. This is called a cell. By wiring up a number of these cells we can make a battery and use it to power electrical circuits.

Converting wind power into electricity seems like an ideal way of helping to solve our energy problems. However, the power generated by a windmill is dependent on the wind speed. If the wind drops to half its speed there is as little as an 1/8th of t....

Parabolic surfaces can be used to concentrate energy for example to focus sunlight to heat things. Using an old World War II spot light mirror we demonstrate how easy it it is to concentrate enough energy to cause combustion. Finally, we show how to ....

Although essentially a very simple device the Gieger Counter is an exquisitely sensitive detector of ionising radiation. It can detect a single particle. Here we demonstrate its use in detecting radiation from minerals and describe in simple terms ho....
