Specification
Material: Aerospace Grade Aluminium + Pure Copper SliderColor: Blue (Earth), Silver (Moon), Gold (Mars)Length: 68mm/2.68''(appr.)Slider falling distance: 38mm/1.50''(appr.) Featuresa.Made from aerospace grade materials, equipped with super precise slider.b.6 Neodymium Magnets inside the Aluminium body.c.Unscrewable top - anodized aerospace grade aluminium.d.Slider-Anodized Aerospace grade Aluminium or pure copper.e.You can flip it, slide it, spin it and fidget any way you like.f.You can compare the Gravity between all three - Earth, Mars and Moon.g.Designed with science in mind and crafted using amazing laws of physics.h.Moondrop is a satisfying fidgeting toy, you will enjoy playing around with it.i.What makes it really unique is it actually displays different gravity than it is on Earth.j.The sliders of Moondrop are precisely made to free fall in the correct speed that imitates either Lunar or Mars gravity. Moondrop Lunar: The slider is made from Aerospace grade aluminium. The distance of falling slider is 38 mm. The time for slider to fall that distance is 0,22 s which is the same as for any object dropped on the moon and falling it's first 38 mm. Moondrop Mars: The slider is made from pure copper. The distance of falling slider is 38 mm. The time for slider to fall that distance is 0,13 s which is the same as for any object dropped on the Mars and falling it's first 38 mm. Moondrop Earth: Turn any of Moondrops into Earth version by removing the magnets and compare the gravity between all three. Why We Call It "Moondrop" ?Moondrop is to imitate the Lunar gravity. It is precisely calculated so vertically falling slider moves at similar speed like you were dropping any object on the lunar surface. The gravity on the Moon is 1,6 m/s² which is only about 1/6th of that on Earth. Since there is vacuum on the moon there is also no air resistance - this makes any object no matter how big free fall in the same speed. How cool is that? Package included:
