Product Overview

This vertical hand boiler is as fun as it is educational. Dramatically illustrates the relationship between temperature and pressure by demonstrating that as temperature increases, so does pressure. Simply place your hand around the bottom bulb, and watch as the liquid races to the top bulb. Recommended for children ages 7 and up. Colors will vary.
