A rattleback creates one of the most inexplicable phenomena in the world of science. Measuring 10cm in length and made using high-quality steel alloy, the device will swing counter-clockwise with ease, not unlike a top.
However, once you try to swing it clockwise, you’ll witness a spin-reversal and will rattle until it comes to a complete stop and reverses its direction. An ancient toy also known as a Celtic or Wobble stone that has been enchanting people of all ages for centuries.
