I don't know, I think it's the fact that everything just turns to dust, and did you see the one with the glowsticks? It looked proper amazing when it was blending... and the one with the iPad where he had to snap it in half before putting it in, that was pretty cool too, lol.
And actually yeah you're right... me owning a blender wouldn't be a good idea afterall, oh well... a man can dream.
