Now it remains to bend the legs of the LED, observing the polarity and calculating the distance from the " " contact to the LED by the size of a carbon tablet: Naturally, because this is an LED, you need to demonstrate it in both polarities, explaining the reason: This can be demonstrated using an adjustable voltage source: I wound it right over the battery: 6. © A. We put in a charcoal tablet, which closes the circuit. So that even thoughts about the “miracle” do not remain, because children must definitely develop critical thinking. I offer 2 options: 1 – short with fun music, 2 – longer with explanations 8. 11. Although the solution is quite easy to read. 3. Not every battery can do this. One
from the ends of the coil we bend and fasten with electrical tape (necessarily blue) to the bare part of the battery: Then we change the tablet to a magnet. Good luck to everyone! To tell that even though the battery is AA, but unusual, not 1.5 volts, but lithium 3.6. 9. From the resulting piece of copper wire we make a coil of any size. There are at least 2 options here: a dead battery and a faulty LED. The second half, which is aware of the impossibility of one and a half volt white LEDs, will definitely not be led to the resonances of the world First you need to clarify that a standard "finger" AA battery produces 1.5 volts. Hello, inspired by a recent post about "perpetual motion", I remembered one video on the Internet, where one craftsman "set fire" to an LED from AA batteries using a coil of several turns and activated carbon tablets. 10. Now is the time to “be smart”, tell about the oscillatory circuit, about the world anti-Ether conspiracy, etc. It looked impressive. Demonstrating the "wonderful" glow of the LED: Pinegin It will not make a trick of the impression: one half of the audience will simply say that what the heck, well, he took a one and a half volt diode, that’s business. 2. 1. Usachev, A. Entertaining the younger generation

Children are a perpetual motion machine, a jumper, a runner, a pusher, a jumper, a grabber, and also a tight hug and a kisser Naturally, there was no clue to the trick. Thank you for your attention. 7.
Focus demonstration: To power the LED, you need about a volt more. 4. Everything is ready for the demonstration of the "miracle". I took an ordinary copper cable 1.5 mm2 and freed one core from insulation: Video versions: I used the first option.

Free energy generator made of activated carbon, magnet and coil. 5. So I decided to make a homemade product in 3 minutes. And now the most important thing is to tell the essence. Next, we need a piece of wire 30 centimeters. To do this, demonstrate the inscription on it, as well as the luminosity of the LED without any tablets, magnets and coils: Be sure to show special joy if an attentive child points to point 3 in which we demonstrated the impossibility of the LED to glow directly from the battery. Next, we take an AA battery and cut off the film from the top for convenience. I won’t advise here, I think you can fantasize a lot: It can now be demonstrated that the LED does not light directly from the battery. It is possible not to cut if it is difficult, but mechanically the final construction will be somewhat more difficult:
