• A gallery with about 100 sq metres of open floor space.
• Electrical power – ten plug sockets.
• The exhibition must be supervised at all times when in use, preferably by staff accustomed to working in an interactive environment.
Wimshurst machine – Turn the handle to create a high voltage spark and watch it leap across the gap.
Human battery – Put your hands on two different metal plates and you can create electricity.
Electric fence – Dare you touch the electric fence? You’ll get a shock if you do… but you won’t die!
Jacob’s ladder – This is an essential component for any mad scientist’s laboratory.

Electro-magnet – Switch on the electromagnet and build a magnetic sculpture from pieces of iron.
TENS machine – Try this medical device used to help relax muscles and relieve pain.
Frog’s legs – Make a ‘frogs leg’ twitch to see how our nerves rely on animal electricity.
Plasma Ggobe – High voltage causes these beautiful sparks and can even light a nearby fluorescent tube.
Electrolysis – Turn a handle to generate electricity, use it to split water into hydrogen and oxygen then ignite the gases and watch the explosion.
Static domes – Rub a cloth on the domes and make the objects inside dance.
Transformer – Move the transformer coils and see have you can make electricity pass through air.
Resistance – Experiment with different components to see why resistance is needed to control electricity.
Switched on – Set the switches in the right order to light the target and sound a buzzer.
Circuits – Place the components in a circuit and find out what happens to the electricity.
