Magic Tricks

I haven't preformed this much (don't always have a table available) but when I do the spectators are real astonished. I preform it similar to Oz in the Demo Vid.
I'v had some hecklers "you just gave them the 2nd card" but all have fallen silent when I "push" the cards into the ballon, & when I pull the card out of the balloon there's a riot. I'v been asked days later "are you the magician who put the cards into the balloon?"
Jay Sankey is a great inventor & I love his tricks
