To demonstrate a piece of ferrite core memory from an old PDP11 computer.

To demonstrate the principles behind the Watts governor.

To demonstrate a cyclic chemical reaction, the Belousov- Zhabotinskii reaction.

To demonstrate Stokes law. This states that when a body moves through a fluid the viscous resistive force is proportional to the radius a and its velocity v.

To demonstrate that a large difference in pressure can create a propulsive force.

To demonstrate standing waves on a string using an electric toothbrush as the vibrating source

To demonstrate the streamline flow around various objects.

To demonstrate the penetrating power of Alpha, Beta and Gamma-rays

To illustrate a simple electrostatic generator that is almost impervious to humidity problems.

To demonstrate the fundamental aspects of the photoelectric effect. In particular that a minimum quanta of energy is required to emit photoelectrons.
