| Objective |
To identify the physics behind some demonstrations. |
| Participants |
Teams of up to six. |
| Materials |
Some of your favourite demonstrations.
1. A gyroscope
2. Crooke's Radiometer.
3. The Cartesian Diver.
4. The jumping ring (an electromagnetic demonstration).
5. A disappearing eye dropper in a liquid of matching index of refraction.
6. Drop a magnet down a copper tube and a plastic tube.
7. Kelvin water dropper - an electrostatic demonstration.

| Rules |
The students have to identify the correct physics involved. This
is one of the most popular events at Physics and Astronomy days
held at the University of Western Ontario. The choices are available
as a set of multiple choice questions, and the students have to
pick the right one and then justify their answers. The discussions
with the Physics Teaching Assistants are the most valuable part
of the competition.

| Judging |
The team with the most correct answers
is the winner. Points are awarded for the reasons given to support
the correct answers. |
