I havent read anything past the first post. but, OP this video is fake.

To prove it, just look at the guy sitting in the hallway with his face "burned" half off.

Notice the huge flap of skin hanging like you could just grab it and peal his face off. Where did that skin come from?
his hair not burned, nor skin around his ear...its fake.

if you were to try to lay that large flap of skin back down, there is no place it would fit properly.
