Is this real, how does it work?

Does anyone know if this video is real or fake, and if it's real does anyone know how it works? http://www.moillusion...jastrow-illusion.html

Sorry to be late, but I've only just seen this. It's not a fake. When I was in the army we could do the same thing with two identical Bren gun magazines.

Do you know how it works, though boo?

Looks like a fraud. One of the pieces of plastic, which is obviously smaller, is removed from camera range. When it's returned it's the same size.

This is another explanation (from the comments at the bottom of the original link):-

This is a very simple illusion you don’t even need to watch the video….

The 2 figures here are Trapezoids and they are obviously the same size. They both have one big side and one small side, and in this picture they are matching the small side from the top figure with the big side from the bottom picture and taking the photograph from an angle were it’s not so obvious, but you can still crearly see that the figure on top has its big side sticking out more to the left than the one in the bottom…

If you were to set both figures with theirbig sides matching, you would crearly see that they are the same size.
