Authored by Professor G. Eric Matthews, this web page describes a project at Wake Forest University to create videos of common physics lecture demonstrations. The goals of the project, the participants, some details...

This video demonstrates that a person can stand on a bed of nails without hurting their feet due to the force being spread out over a large area. It is part of a collection of typical lecture demonstration videos put...

This video shows a demonstration of buoyancy. A small glass vessel with a hole in the bottom is partially filled with water and placed in a partially filled cylinder of water. The cylinder has a rubber diaphragm which,...

This video demonstrates that a ping pong ball can "float" on a stream of air. The air rushing around the ball creates a pressure low enough to lift and support the ball, even when the ball is not directly over the air...

This video demonstrates conservation of angular momentum. When a person on a rotatable platform (initially at rest) tilts the axis of a rotating bicycle wheel, conservation of angular momentum results in spinning of the...
