The trick is a good principle- crush a bottle in front of your spectator's eyes! Unfortunately, when
you watch the video a few times after you get your set, the gimmick is very obvious and it get's
noticed by some spectators. The hands-off version is much better, but I personally figured it out
from a science class I took in school.
Overall, a great idea, but a little disappointing
considering the price for the "bang" value that the trick delivers. There isn't the "wow" factor
that I was expecting to pull out of this trick.
