So very hard for me to recall image after image of cool science. It is all going in but the recall on command is high. The hydrogen bomb egg is just awesome. I cant wait to try the exploding sugar in hot water. It seems so wrong as people's coffee doesn't explode when they heap in those calories. The idea that spark plug ceramic which I think is zirconium will shatter tempered glass is just mind blowing. Sorry, you can see it, but I talk about it.
