its sugar glass like they use in the movies... I worked in the glazing industry for 10 years and its imppossible to cut plate glass in this fashion. If you look closely at the surface of the glass you can see that the reflected light shows a wavy and distorted surface.. don't waste your time, if you try to cut real plate glass in this manner you will most likely cut your self when the glass shatters from the pressure of the scissor

Does sugar glass sound like that when you tap on it? An doesn't it break very easily?

This is definately possible. The edges of the glass don't turn out very smooth however.

It's not the glass that is wavy, look at his hand when you "think" you see wavy glass. It's the shoddy video.

all i have to say is that glass can be cut just put it under water and let it rip

I wouldn't try it, I saw another vid that a guy tried the same thing (with real glass) and he cut himself when the glass broke in a few pieces, he also captured his stitched hand on the vid...

The guy who cut himself also tried cutting a bottle/jar, didn't have it fully submerged, and wasn't securing it while cutting it. In my opinion it's his own fault for not thinking clearly . You can view the video however and come to your own conclusion through this link: http://www.youtube.com/watch?v=LBMtbVonAIg
