Description

This unique thermometer and barometer combination is perfect for the weather enthusiast or someone who just loves science. This functional and attractive decoration features a thermometer based on Galileo's (1564-1642) discovery that the density of fluid expands and contracts depending on temperature. The density of the liquid in each sphere varies slightly and as the actual room temperature fluctuates, the glass spheres will rise or fall. The water level in the barometer rises and falls with the changing of the air pressure. Now you can forecast the weather in the most elegant way. Recommended for children ages 10 and up.
