The Artificial Balloon

Take a bladder containing only a small quantity of air, and a piece of

lead to it, sufficient to sink it, if immersed in water. Put this

apparatus into a jar of water, and place the whole under a receiver.

Then exhaust the air, and the bladder will expand, become a balloon

lighter than the fluid in which it floats, and ascend, carrying the

weight with it.
