Air Borne (for Soda or Wine) by Mr. Magic
The magician shows one empty glass and a full bottle of coke. He proceeds to pour the beverage into the empty glass. As he lifts the bottle higher and further away from the glass, he removes his hand from the glass and it looks like the glass is floating in the air while the soda continues to pour!
Includes gimmick, plastic drinking 'glass' and instruction sheet.
