With Crazy you make the audience crazy.

In "Verrückt" (crazy) , plastic parts that are closed on all sides and hang on a rod that is blocked on both sides are moved (in the sense of "moved").

The four pieces in red and white cannot be taken off the rack , and yet they are constantly being regrouped:

First they hang in the order red/red/white/white,
then red/white/red/white,
finally white/red/red/white
and then red/red/white/white again.
Crazy is inscrutable.

>>> Everything can be examined before and after the demonstration!!!
