Converting anything into heat is dead easy. Anything that absorbs sound is converting it to heat.

The comments section discusses, which includes

Sound energy is very low. The often quoted “fact” is that if a crowd in Wembley Stadium cheers very loudly for 1 minute, there is barely enough energy in that total noise to fry an egg.

Would be more efficient lighting their farts… :nerd_face:

I don’t care about the explanation this is magic shit right here.

Gyroscopes. If you think you understand them then you almost certainly don’t. Eric Laithwaite showed this thirty-odd years ago. Indoors. Where the consequences of inadvertently dropping it can be very exciting indeed.

He was a controversial character. It was argued hotly at the time whether his gyroscope demos (there are quite a few on Youtube) clarified or confused people’s understanding of the subject. The fact is that gyros don’t break any laws of physics. But predicting what they will do requires a grasp of dynamics that very few people indeed ever achieve.

Like his t-shirt as well :grinning:

Just watched the Laithwaite video. I still think it’s magic but could the weight be scaled up? Both videos use a 40lb weight. Is there magic something about 40lbs?
