Hydrostatic Milk Bottle

A rare find in this condition.

The Hydrostatic Milk Bottle is now quite rare in this version. A large milk bottle is filled with liquid (you could use OOM to represent milk). The open end of the bottle is covered with a card, and the bottle is positioned upside down. As the card is slowly removed, it appears astonishing that the liquid does not flow out of the bottle. At the performer's command, the liquid then drops freely, creating the illusion that gravity has been temporarily suspended.
