Neutral buoyancy diver maintains neutral buoyancy by continuous correction, usually by controlled breathing, as neutral buoyancy is an unstable condition for a compressible object in a liquid. The mathematician Archimedes discovered much of how buoyancy works more than 2000 years ago. In his research, Archimedes discovered that an object is buoyed up by a force equal to the weight of the water displaced by the object. In other words, an inflatable boat that displaces 100 pounds (45 kilograms) of water is buoyed up by that same weight of support. An object that floats in the water is known as being "positively" buoyant.
A Funny Thing Happened on the Way to the Forum sprinkles some of the horse-sweat onto him, then suggests that the road trip has left Senex in dire need of a bath. Taking the bait, Senex instructs Hysterium to draw him a bath in the long-abandoned house of Erronius.

Erronius immediately determines to have
