Fidgets are a real paradise and a nightmare this year. It seems that these are the most sensational gadgets - and even Apple and Xiaomi do not create so much information noise.
These devices are needed to treat attention disorders, increased irritability, and simply kill time. About spinners And mnushki we have already told you. Now the shelf of devices for “twist-twirl-click” has been replenished with another product from Kickstarter: Firestar - “Fire Star”
What is Firestar?
Firestar is a unique magnetic stick (stick). A ring runs between the two ends of the stick. The trick is that it moves at the wrong speed: instead of obeying the law of gravity, the ring in the “Fire Star” seems to be in the atmosphere of Mars or the Moon.
Real magic! Anti-gravity! Levitation - just a little bit. Although everything is simpler - Firestar works using Lenz’s physical law. The base of the Firestar is made of aluminum, and the ring around it is made of copper or aluminum. A powerful neodymium magnet is hidden inside the wand.
How does Firestar work?
Copper and aluminum are not magnets, but they are excellent conductors of electricity. The magnet inside emits a magnetic field. When a magnet is passed through the ring, the magnetic field induces an electric current in the copper or aluminum.
According to Lenz's law, the current creates an opposing magnetic field, which slows down a moving magnet (or vice versa, a ring - you can look at it in any way). Depending on the ratio of the conductivities of the magnet and conductor materials, different sliding speeds can be achieved.
So what does Firestar do? You turn it over and the ring slowly falls along the stick. It's like gravity doesn't act on him. More precisely, it works. But - not earthly!
The aluminum (gray) Firestar moves the ring at the same speed it would fall on the Moon. And gold (copper) is like on Mars. An incredibly simple way to see a piece of other planets without leaving your stuffy office. Although, “Fire Star” will be useful to many.
Who should buy Firestar?
1. For a true fidget lover! Each fidgerer gets a “Fire Star!” It will appeal to anyone who likes to hold something in their hand, move it, turn it, click it. With any movement of the magnetic ring, it comes to a state of “weightlessness”.
2. For researchers and science enthusiasts. Firestar is a great way to see the effects of weightlessness on earth, without labs or special preparations.
3. All lovers of cool gadgets cannot do without a real geeky fidget.
4. This is a great gift! Simple, elegant - and amazing.
5. Firestack will appeal to modern technology lovers. The stick fits perfectly in the palm, made with an accuracy of up to 0.01 mm. Amazing toy!
6. Without it, there is no way to prepare for a flight to the Moon or Mars!
Is Firestar the best fidget?
Certainly! Spinners made a splash, but did not lead to a real therapeutic effect. And “Fire Star” also shows how objects move on other planets.
