Three glasses are covered with three differently colored bags. The viewer is given the choice to select two colors. It is a guaranteed free choice!
The viewer can change his mind at any time. So while the spectator has chosen two colors, you are left with the third. And the viewer will always get nothing while there is a banknote or other gift in your glass.
In the case of children's performances, you can also handle it in such a way that the children each receive a candy while there is only a blank piece of paper in your glass.
You will receive four bags and German instructions. You can use your own glasses/cups.
