- 7" Thermometer: Ranges from 64 to 88 degrees Fahrenheit and contains five spheres in 4 degree graduation.
- 11" Thermometer: Ranges from 64 to 80 degrees Fahrenheit and contains five spheres in 4 degree graduation.
- 15" Thermometer: Ranges from 62 to 86 degrees Fahrenheit and contains seven spheres in 4 degree graduation.
- 17" Thermometer: Ranges from 66 to 84 degrees Fahrenheit and contains ten spheres in 4 degree graduation.
Galileo Thermometers demonstrate a uniqe method of telling the temperature that was discovered by Galileo Galilei (1564-1642). The balls inside the glass have different densities. When the temperature changes, these balls rise and fall. To read the temperature, check the group of balls near the top. The lowest ball of that group tells the temperature. If all the balls are at the bottom, it is hotter than the temperature of the top ball. If they are all at the top then it is cooler than the temperature of the bottom ball.
For best results, keep out of direct sunlight.
