To help a general public understand the difference between matter and antimatter


This hands-on exhibit is part of the exhibition module #6 "Where is the Antimatter?" of the exhibition "Weltmaschine". It teaches exhibit visitors how similar yet different matter and antimatter are by representing each with a box of sand.
The module consists of two transparent, containers (80cm x 80 cm x 80 cm) filled with sand. One container is filled with 1 billion grains of black sand (= anti-matter), the other is filled with 1 billion + 1 grains of white sand (= matter).
