Every time the trick is performed costs you 3 balloons, the expensive latex balloons too. The
method is clever, but like another reviewer wrote, it's a pain to set up each time. I would advise
only performing this for your paid gigs so you can recoup some of that loss and make it worth while.
I feel there is a lot more to be explored with this principle. I fooled with pulling a
card through the balloon using this method years ago. It worked with a folded card, but it was too
much trouble.
