The Steam Gyro

The very first steam engine was a spinning copper ball, invented by Hero of Alexandria in the first century.

This swimming spin top uses the same principle. A tea light (not included) heats the water in the copper spiral and recoil from the steam makes the Gyro spin. Then the steam condensates and sucks fresh water into the pipe. This process is repeated several times per second as long as the candle burns.

A neat little model that fascinates young and old. Add a paper cylinder and turn it into a spinning buoy, a revolving lantern, etc.

The kit contains a cork plate (80 x 10 mm) with pre-drilled holes, a copper spiral with soft-annealed ends, and a bending tool. Construction time: 15 min.

A thin strip with grooves carved into one side is connected to a resonator. The recorded sound can then be played back with the nail of your thumb.

Comes with four messages:

“Merry Christmas”, “Happy Birthday”, “Congratulations”, and “Good Morning”
