This very simple toy uses a magnetic chain reaction to launch a steel marble at a target at high speed. The toy is very simple to build, going together in minutes, and is very simple to understand and explain, and yet fascinating to watch...
Featured science project Beginner 1
The purpose of this experiment was to find out if the number of wire wraps will effect the amount of iron filings an electromagnet picks...
Featured science project Beginner 1
This is a great demonstration of like poles repelling each other. We have a platform which floats above a pair of magnetic tracks, and can be gently pushed to one end or the other. This is similar in concept to the MAGLEV trains which...

This home page features award-winning, easy-to-build, and inexpensive electric motors. If you are looking for a simple science project, or if you wish to learn about electricity, magnetism, and electric motors, this web site has it all!...
Featured science project Advanced 7
These plans are for the construction of a machine called a Savonius wind turbine. Wind turbines come in two general types, those whose main turning shaft is horizontal and points into the wind, and those with a vertical shaft that points...
Featured science project Advanced 7
You can make your own telegraph for sending secret messages to a friend. This project may require a trip to the store, some patience, and maybe a bit of help, but it's well worth it. After connecting all your wires and buzzers, you'll be...
Featured science project Beginner 1
The toy is a high voltage motor that acts like a bell, with a clapper that bangs furiously from one can to the other and back again, sometimes several times per second....
Featured science project Beginner 1
A hand-held electrophorus can produce significant amounts of charge conveniently and repeatedly. It is operated by first frictionally charging a flat insulating plate called a "cake". In Volta's day, the cake was made of shellac/resin...
