Swinburne Science Show (Part 2 of 3). Circa 1978.

Sections of this part include:

1. A thump from a pump
A demonstration of converting and storing energy.  When the lower chamber is opened suddenly, the energy converted from the air pressure is enough to crush a steel pellet.

This is followed by a small chemistry demonstration of changing the colour of liquid like magic, and a puzzling demonstration of a balance.

2. The case of the curious case
A suitcase appears to stay up like magic as it turns on a small platform.  This is a demonstration of gyroscopic precession, using a gyroscope mounted inside a suitcase.

3. The moon's a balloon, then
When two balloons are connected and air can flow between them, the balloon with less air curiously deflates and gives its air to the balloon with more air.
