That's amazing and a bit scary. The magnetron video - where they take the magnetron out of a microwave oven (but leave it connected) and then tie it to a stick and point it at stuff with the oven (and thus magnetron) powered on is scary.
At least the trick with old CRT is fake (as one YouTube commenter noticed) - it can be clearly seen in TV screen reflection that someone throws something towards the TV just a moment before it breaks. And if you look closely at the garbage before the TV -- a gray brick appears there just a moment after the "explosion".
