I don't get it... my face was like O_O at the end of the video

he uses e=mc^2 to explain how his "energy" goes into produce "mass". But can it be explained from a more mathematical/geometrical perspective too?

I think if he not "palming" the extra pieces and doing a streaight forward video editting trick then he is probably using the illusion illustrated in these tricks.

We've had countless discussions on this triangle "paradox". If you look closely, it's not a triangle. I don't believe it has a uniform slope.

It is a well known thing dude. The hypotenuse is not a straight line :) ... no E = mc^2 funda here.
