Ok thats it, Fidget Spinner trend is over, cause this is the best one ever!! 😉 I built a custom fidget spinner out of 1/4in aluminum plate and strapped 3 E sized rocket engines.

Really, I just wanted to do this. I saw Stephens video and needed answers. Plus, this gave me an excuse to buy a Plasma Cutter ive been eyeballing for yearssss. (dont tell sandra I could have made this with a jigsaw..)

The spinner has a 6 inch radius, so it travels ~37 inches to make a full circle. Its spinning 88 times per second (5200 per minute), so that means the tip is traveling 276 feet per second, or 188.182 MPH. so yeah, 1000mph fidget spinner is pretty much impossible… Who will accept my challenge?

Exploding soda cans with electromagnets in SLOW MOTION ft Joe Hanson

Making Music with a Tesla Coil:

Watch a soda can rip itself apart in a fiery explosion at 11,000fps with a Phantom high speed camera. Running a current through a coil, produces an electromagnet. Turn up the voltage in this experiment, and make that current strong enough, and your electromagnet can rip a soda can in half. Or rather, make the can rip itself in half! This video was filmed at Arc Attack Studios in Austin, TX with Joe Hanson, Joe DiPrima, John DiPrima and Darren Dyk.

How the quarter shrinking demo works:
A coil of wire is wrapped around the quarter so it follows the edge of the quarter. Then a capacitor – kind of like a battery – is charged until it’s at a VERY high-voltage, which is then discharged through the wire. The current produced is high enough to make you go bye bye. The coil becomes an electromagnet – because current —≥ magnetic field But this magnetic field creates another current or set of currents in the quarter – because changing magnetic field —≥ current in a circuit. But moving charges, i.e. currents, in a magnetic field will feel a force. For the quarter, the charges moving in the edge are feeling a force inward. The current was SO strong that the quarter PULLED ITSELF inward! This is madness.
