Galileo Thermometers Make Great Executive Gifts! Experience the captivating qualities of the Galileo Thermometer based on the discoveries of Italian scientist, Galileo Galilei. Each elegant, liquid-filled glass cylinder holds five weighted glass balls that are filled with intensely colored liquid. The glass balls all have an attached temperature tag and will float or sink according to the current temperature. This fascinating method of measuring temperatures can help you relax during a long and stressful day.
A Galileo Thermometer will enhance your work space and makes a great executive gift. You can read a Galileo Thermometer by looking at the lowest floating sphere in the upper part of the cylinder. Each sphere is calibrated to have a certain density. If it has a higher density than water at a certain temperature, it sinks. If it has a density that is lower, it floats. The sphere calibrated closest to the temperature the water is at will float in the middle or at the bottom of the highest floating baubles.
