This exhibit displays one major way of heat transporation:
convection.
The visitor sits on a chair, and turns the pedal generator, which heats
a resistor in the water tank. Raising warm water is seen as a shadow of
smoke on the screen, when lit by focused light.
This exhibit is very popular due to its high level of interactivity.
Maintenance: Replace (deionized) water every third month.
