Is man more intelligent than an ape? Before you answer, look at this experiment.

One of the most important research institutions in Germany, the Max Planck Society, organized this curious experiment which compares the ability of man and apes. Participants are required to remove the nut from the tube using ANY means possible and without overturning the table. In the end, after they all failed, a monkey shows them how to do it: pour the water in the tube. Who's smarter?
