omg just look at this, how the f*ck is this possible? really impressive http://gprime.net/video.php/theglasstrick
its an optical illusion, i dont know how, but why else would he be using clear glass, which from that angle and distance you cant really tell the depth of it
man did u see the vid? i mean he passes an entire salt container (or what the hell it is) through the glass. u can tell the size of the glass it isnt that hard, i would say its about 2-3 cm thick. i know its an illusion or something but thats impressive.
yeah, it is easy to manipulat the brain, i mean, i see people flying and putting things through tables all the time. Edit: if you cant tell im being sarcastic, you need help ^_^
