- This colourful GLASS GAILEO THERMOMETER is 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 44cm TALL glass tube holds TEN floating baubles each filled with colourful liquids of different densities, each bauble has a silver-coloured tag that indicates the temperature from 16°c to 35°, this fun weather station is a fun way of taking an accurate temperature reading in your home
- 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
- This temperature thermometer will make a fantastic novelty gift for a loved one or the most perfect housewarming gift and will also look great as a desk gadget
