Fahrenheit hydrometer

A Fahrenheit hydrometer is a special type of tool used to measure the density of a liquid. It works by measuring how much of the liquid floats in a tube. If the liquid is more dense than the air around it, the liquid will sink and the hydrometer will give you a number (in Fahrenheit) to tell you how dense the liquid is. The more dense the liquid, the higher the number it will give you. Hydrometers are used in science and engineering to help scientists understand liquids and make sure that things like drinks are safe for us to drink.
