Magnetic Lodestone

A large 1" x 1" magnetic rock, which was made into a magnet by the earth's magnetic field. The magnetic field in a lodestone decreases over time. If the earth were "billions and billions" of years old, then its magnetism would be gone. But, it is not, so each lodestone must be "young" (probably less than 10,000 years old). This is difficult for an evolutionist.

Bumper Balls Magnetic Puzzle

Learn about the "principle of the Conservation of Momentum" first hand with this fun magnetic game. In a clear plastic tube there are three magnetic balls. Outside of the tube are two ring magnets. The trick is to separate the three magnetic balls so that they "float" by themselves in the tube when the tube is held vertically. Great fun for ages 7 and up.
