The magician holds a wine bottle in one hand and an empty wine goblet in the other hand.
He begins pouring wine from the bottle into the glass then lets go of the glass.
The glass magically stays suspended in mid air and then moves FURTHER DOWNWARD and then BACK UP again at your command as the wine continues to pour into it.
An excellent stage effect! The bottle looks great, and the glass is frosted for a classier look!
