This artwork by David Durlach works with magnetic fields. Magnets are covered with very fine iron powder. The exhibit also contains many tiny coils of wire. When electricity flows through them, they become magnetic, changing the pattern of the magnetic field. This makes the iron powder “dance”.

Try to hit the wall with as much power as you can. The harder you smack the wall, the higher is the so called "smack factor" displayed at the monitor. This force is related to your mass. Thus via the factor you can compare the power of children to those of adults.

Mindball is a two-person game controlled by your brainwaves. Your brainwaves are detected by sensors on the headbands, connected to a biosensor system. The biosensor system registers the electrical activity in the brain. The most relaxed player wins the game by making the ball roll over to their opponent´s goal.

The glass globe contains a mixture of inert gases at low pressure. There is a high-voltage electrode in the centre which passes electicity through the gas and makes it glow. The glowing gas is called “plasma”. The hand of the discouverer acts like a lightning conductor and draws the stream of plasma towards him/her.
