you know, ive just remembered that i used to....
fill a paper cup up to its brim
place it into a paper bag
place the bag on their head ( spilling a bit on the way)
then after a bit of buiseness, Id crush the bag, vanishing both cup, and water.
this always got great reactions. and there wasnt a slush, or a foo in sight.
The effect is one of George Kovaris, and he published it in his pitch book, that he used to sell after his large shows.
I really think i should start doing that one again!
