Galileo Galilei: Floating Thermometer

Galileo Galilei's birthday is coming up (he was born on 15 February in the Year 1564). He is an Italian POLYMATH --no wonder his name lives on. He was blessed with a vast amount of head knowledge; and knew just how to put them together to good use. Thank God for him!

The floating thermometer was not invented by Galileo, but is named after him because "... he discovered the principle on which this thermometer is based—that the density of a liquid changes in proportion to its temperature".

Daughter's gift from me and hubby.  Fascinating to watch.
