Most things float or sink! Ask students: How it is possible for the blue disk to remain in the middle of the liquid? This fascinating thermometer uses a disk connected to a tethered chain to measure temperature. As the temperature decreases, causing the density of the liquid to increase, the disk floats higher. The interesting part is that as this happens, the disk supports more and more of the chain, thus becoming heavier. Reads in both Celsius and Fahrenheit. 18 cm x 18 cm x 4.4 cm (7" x 7" x 1.8") Two Year Warranty.
