An 84-lb weight is lifted as a result of a vacuum.

Liquid in a test tube has 2 paths when gravity is allowed to act, but only one is accurate

Water is siphoned from one container to another

Air is evacuated from the Magdeburg Hemispheres, after which they cannot be separated.

A U-tube has both water and kerosene in it.

A piece of newspaper is placed over a piece of lath.  The atmospheric pressure on the paper prevents the buried end of the lath from raising when the open end is struck, resulting in a broken board.

A small beaker of copper shot is sunk in a large beaker of water to demonstrate measurement of the buoyant force.

A wood block placed in a vat of water displaces water without changing the overall mass of the container.

A container of water with 2 holes (one above the other) demonstrates the differences in fluid pressure by depth.
