Hydrostatischer Blasebalg

Experimentalinstrument zur Veranschaulichung des hydrostatischen Paradoxons.

Beschreibung in Comstock 1850: “An instrument called the hydrostatic bellows, also shows, in a striking manner, the great force of a small quantity of water, pressing in a perpendicular direction. This instrument consists of two boards, connected together with strong leather, in the manner of the common bellows. It is then furnished with a tube a, which communicated between the two boards. A person standing on the upper board may raise himself up by pouring water into the tube. If the tube holds an ounce of water, and has an area equal to a thousandth part of the area of the top of the bellows, one ounce of water in the tube will balance a thousand ounces placed on the bellows.”
