Visitors touch different materials with two electrodes. If they touch a conductor, a signal sounds and they can read the current on a meter. One material is wire with a high resistance, so visitors can read the changes in current.

Visitors are challenged to move the entire stack of disks to another rod, obeying the following rules: Only one disk may be moved at a time. Each move consists of taking the upper disk from one of the rods and sliding it onto another rod, on top of the other disks that may already be present on that rod. No disk may be placed on top of a smaller disk. With three disks, the puzzle can be solved in seven moves.

Visitors can create their own wind turbines by attaching blades in different shapes and sizes onto freely rotating turbine hubs. They can then turn on the fan and carry out their own tests to find out which blades make the best turbine, or which direction is the best.
