At long last…we have this effect that magic world has waited for. A reasonable price for a unique effect! The bubbles multiply in your fingers, ala “Multiplying Billiard Balls” and what’s nice about this set is that they are NOT real glass! IF you drop them, they won’t break yet at a close up scenario, you cannot tell that they are not glass! Now you can add this to your manipulation act without fear of breakage and still show something different!
