The demonstration were given at the 7th December 2011 in front of the aula of the main building university of Bonn. We had no tatami (mats) available and were very carefully to take the ukemi (falling/rolling) part. As usual we didn't rehearse for it to give an authentic flavour to our performance. The uke (those who accept the defeat) are participants of the Hochschulsport of the university of Bonn, namely Christian, Constantin, Florian, Jan, and Johannes. Joann was our creative director.
