Effect
A glass filled with water is placed on the magicians left hand (palm up). Covering the mouth of the glass with his right hand he turns the glass upside down. Now holding the glass with his left hand he releases his right hand. To the surprise of the everybody the water does not fall out. On the count of three all of a sudden the water stars falling into a bowl. A great display of anti-gravity effect indeed.
Comes complete with glass and instruction sheet.
