The notorious Frankfurter Illusion

Weird Gadgets here  at Funny Junks

If you have two roughly equivalent eyes you will see a ‘sausage’ floating in front of you in mid air, by following these steps:

1. Hold your hands in front of you, at 20–30 cm distance from you, at eye level.
2. Point your index fingers against each other, leaving about 2 cm distance between them.
3. Now look “through” your fingers, into the distance behind them.
4. The sausage should appear now, and you can change its length by varying the distance between the finger tips.
5. For most observers, the sausage will look blurred, at least initially.
6. If you try to look at the sausage, it will disappear, it is only present if you look at something more distant than your fingers.
7. It helps if the background is rather homogenous and has a color very different from your fingers.

Find the Face (in the Beans)

Weird Gadgets here  at Funny Junks

Find the face among the beans – The picture on the right is floating around the Internet. I do not know the original source, which I really would like to cite. Please communicate!

The picture is accompanied by all sorts of inferences on your mental development depending on delay until you find the face in there, which are, hmm, lame, even though they begin with “According to recent medical evidence…”.

By the way: Yes, there really is a face in there! Once you’ve seen it, there is no doubt any more
