Gemstone Donut Pendant
Wear your love of geology around your neck! This beautiful Gemstone Donut Pendant is available in six different gems.

Spark your curiosity for electricity and physics with your very own Wimshurst Machine.

Invented in the 1880s by James Wimshurst, the Wimshurst machine is an electrostatic generator that uses rotation to create high voltages!

Just like the scientists who pioneered our understanding of electricity, you'll learn one of the ways that electrical current can be generated using your own two hands.

If you've ever wanted to know how and why electricity - the basis of modern life! - works, this is the machine for you!

How Does it Work?
The Wimshurst machine, invented by British inventor James Wimshurst in the 1880s, is an electrostatic generator.

The machine is able to generate high voltages through the contra-rotation of two discs, often made of glass. The discs are insulated with a metal section and rotate in opposite directions. As the discs rotate, charge is collected on metal combs. As soon as there is a difference in charge between the two discs, the charging process begins.

This charging process is a positive feedback loop, and increases the polarisation of the two sides of the disc. This polarisation increases until there is enough built up charge in the attached Leyden jars to create a spark between the two.
