The Physics Behind Four Amazing Demonstrations—David G. Willey

It is interesting how many seemingly impossible or dangerous things can be done if you understand the physics behind them and what is actually going on. I have heard of some of the demonstrations and how to do them before but not all of them. Walking on glass sounds like it is very easy but can also be very painful if you do not prepare properly for it. The nail of beds looks like it would be uncomfortable to lay on but not necessarily that painful. Getting hit by a sledge hammer does sound like something I would not want to try just because the chance of being hit too hard and being punctured by the nails.

I have not heard of the other two demonstrations. The molten lead still sound like it would be a dangerous demonstration to do and I still don’t fully understand it. How long do you keep your hands in the lead and how wet do you need to have your hands in the first place. I would not want to risk my hands to try to impress my friends. Picking up a orange hot piece of space tile sounds like it could be a fun trick. I would like to be able to take one of those tiles and try this one out. I wonder how quickly the tile will lose its orange color since it cools off so quickly.
