FRAGILE indoor hand blown glass thermometer based upon the principles discovered Galileo Galilei (1564-1642) involving the temperature dependence of water density. The cylindrical glass thermometer is filled with a special clear liquid containing 7 hand blown glass orbs. Each orb is filled with colorful liquid of varying density which rise and fall as the fluid temperature changes. Each orb has it's own silver colored tab attached. The tags range from 68 to 80 degrees Fahrenheit in 2 degree increments. There are many tutorials on-line with detailed instructions on reading the thermometer
