This SET of TWO colourful GLASS GALILEO THERMOMETERS are based on Galileo's theory that was established 400 years ago, in liquid, a body of fixed mass becomes less buoyant as the liquid temperature rises, and becomes more buoyant as the temperature decreases, due to changes in liquid density.
As the temperature changes, the multi coloured floating globes RISE and FALL within the liquid filled thermostatic tube. The lowest sphere in the top group within the INDOOR THERMOMETER indicates AMBIENT TEMPERATURE.
The 30CM TALL glass tube holds SEVEN floating baubles each filled with multi coloured liquid of different densities, each bauble has a silver-coloured tag that indicates the temperature from 16°c to 28°, this fun weather station is a fun way of taking an accurate temperature reading in your home
One of the thermometers has multi coloured baubles whilst the other one has electric blue coloured baubles, fantastically stylish and cool to observe, this interesting water thermometer is sure to be a hit with those mad about science, it really is simply fascinating, the tags on the baubles are marked in both CENTIGRADE and FARENHEIT measurements
These temperature thermometers will make fantastic novelty gifts for a loved one or the most perfect housewarming gifts and they also look great as desk gadgets.
