Magic Tricks

In Germany we say "outside hooey, inside phooey" (All fur coat and no knickers.)
The effect is already impressive ("outside hooey"), if we disregard the unavoidable noise. The material is cheap, and it's only a matter of time when the elastic band stops working ("inside phooey"). The produced material has to be fixed by double-sided adhesive tape or similar, i.e. it cannot be taken out after the appearance. The video explanation is very short and should have been more detailed.
In my opinion the trick is a dazzler and completely overpriced. Two stars only because of the effect.
