Play with gravity with the Moondrop Gravity Defying Fidget Desk Toy. Drawing inspiration from space missions, Moondrop is a fidget desk toy that imitates the Mars and Lunar gravity. It features a vertically falling slider that moves at a similar speed like dropping an object on Mars or the Moon. Additionally, by merely removing the magnets, you can turn other Moondrops into an Earth version. Likewise, this allows you to compare the gravity of the three space objects. Using aerospace-grade materials, Moondrop is fun to fidget with, slide, flip, and spin. It is also an educational tool that makes it interesting to learn the laws of physics and facts about our universe. Furthermore, Moondrop comfortably fits in your pocket so you can take it with you anywhere.
