Hi guys there is an effect where you can cause the bottom of a glass bottle to smash while the spectator is holding it. Its been around for a while and there are similar effects with a light bulb too. I would really like to know the name of these effects if they're published.
Here is a video of Keith Barry performing it and I'm sure I've seen David Blaine perform it too.
(effect starts at arround 11:50)
