Trick is good but I didn't realize it has to be very cold initially to work properly. This could be
a giveway to an audience member to feel when you hand it to them. I have a problem keeping it that
cold for any length of time before you show it. I solved this by making a small foam cooler and
filling it with crushed ice and putting it in the ice after I straighten it out. It will remain
fairly flat for a few minutes out of the ice and then hand it to an audience member.
