Mirror Optical Illusion Prank that involves identical bathrooms and twins

This is quite an interesting German prank that fooled many. It required a lot of preparation of the scene and the actors involved in this prank.

In this amazing optical illusion, a pair of twins stand each other in a bathroom which is the exact reflection of the other bathroom. The bathrooms are separated by what seems to be a mirror, but in reality is just a very clean transparent glass. One of the two bathrooms is sealed so that people enter on only one bathroom. The twins have learned to move and walk as if one were the reflection of the other; they have also learned to talk at exactly the same time.

Whomever enters the bathroom that is available encounters one of the two twins who acts very normal given the circumstance that she might be talking to a person without a reflection, maybe a vampire! There is one case in which a man enters the bathroom, and he is so freaked out about not having a reflection that forgets that he just entered maybe a woman's bathroom. In all, a great optical illusion prank excellently executed.
