Physics Demo Manual

Demonstrations are cataloged according to PIRA Bibliography


Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

Gauss Gun - Elastic and Inelastic Collisions


A dramatic way of demonstrating elastic and inelastic collisions.


This is a glorified version of the executive toy. Set up several bunches of 3 ball bearings attached to a single neodymium magnet on the u-shaped track. Overall we have 10 magnets so 10 bunches can be set up at most. Slightly roll a single ball from the side of the magnets and see the last ball in the series to come off with great speed.


This demo can be used as a mechanical model of a linear accelerator or even as a simple demo of a photoelectric effect.
