Links to useful demo sites, descriptions of dangerous and not-so-dangerous electrical demonstrations, and some unusual scientific projects.

Physics-related word-problem puzzles.

Animated experiments and visualizations on physics with theoretical explanations. There is also a physics forum, free samples and educational programs for download.

From the University of Maryland Department of Physics. Each week a new question will be posted and the answer for the previous Question of the Week will be shown. The questions involve real experimental physics, so part of the answers will be photographs and short videos of the experiments carried out in determining the results.

Animations and photos show how these cranes are able to lift thousands of pounds using hydraulics, and how these machines are operated.

Tarzan (a water balloon) is swinging on a thread which is cut by a hot wire mid-flight; students must project Tarzan safely through a hole surrounded by pins.

The project described at this web page was undertaken to develop a set of demonstrations having clear relevance to manufacturing and commercial operations. Some of these demonstrations should also serve to augment the science teacher's or hobbyist's bag of tricks by making it easier to reinforce the relationship between basic principles and practical situations.

Part of Bill Beaty's amateur scientist pages. Includes many links to his and other demonstration sources.

A large collection of online demonstrations that illustrate a variety of physical concepts.

Physics demonstrations, descriptions, discussions of the physics, and hazards to avoid. Groupings are light, magnetism, electricity, sound, heat, and motion.
