Gravity defying desk toy that imitates the free fall on Mars and Moon;
Amazing laws of physics combined with precision machining;
You can flip it, slide it, spin it and fidget any way you like;
Why we call it Moon Drop?
Originally we designed Moondrop 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/s? 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 ?
During the prototyping process idea evolved and we created the second version with copper slider that imitates the free fall on the Mars. You can compare the Gravity between all three- Earth, Mars and Moon.
Why do I need a Moon Drop ?
1. You are a Fidgeter. Just like us you always love to hold something in your hand and of course- spin it, roll it, slide it, click it and fidget around in any way possible. The ''anti-gravity'' slider makes it very satisfying to play with Moon Drop. We found fidgeting a great way to keep focus, not get distracted from meaningful works, relieve anxiety or just relax.
2. You are an explorer or science enthusiast. Moondrop is a pretty cool way to learn about amazing physics laws and science facts in our Universe and share them with others. It is much more exciting to actually see and feel the process instead of only hearing theory and numbers. People are amazed by the gravity defying movements and they get even more interested after hearing the idea behind Moondrop.
3. You love cool gadgets;
4. You like to amaze your friends. Give them unique present and show how objects fall on the Moon.
5. You are into high quality stuff. Moon Drop is CNC machined from Aerospace grade aluminum and pure copper with precision up to 0.01 mm.
6. Plan on going to the Moon? Well, you should try its gravity first.
How it work?
The surprising movements of Moon Drop are caused by Lenz's law which is well known in physics world. Moon Drop is made from pure copper or aluminum ring, aluminum body and strong neodymium magnets inside the thin aluminum tube.
Copper and aluminum is a non magnetic material however they are great conductors of electricity while each magnet is surrounded by its own magnetic field. When the magnet moves through conductor such as sliding copper ring its magnetic field induces an electric current in the copper. According to Lenz's law that current creates an opposite magnetic field that adds certain resistance to moving magnet. That makes the slider move slower than it would normally do if made from other materials (without electrical conductivity). Depending on proportions between magnet and conductor different sliding speed can be achieved.
