Size–weight illusion

The charpentiersche deception, also called size - weight illusion is a perception deception. It is when two identical heavy bodies appears easier with the larger volume. So brought a 10 liter bucket filled with water, while wearing the impression that he had a lower weight than a 10 kg heavy brick.

The description of the effect from 1891 is attributed to Augustin Charpentier ( 1852-1916 ).
