Is it possible to create a Galileo thermometer by hand with house hold items? What are the physics and mathematics behind the Galileo thermometer and how can I solve them to use different densities of liquids?
I want to attempt to create a Galileo thermometer (or a few if possible) as a science project that uses various liquids that have different densities at specific temperatures. I understand the fundamentals of how the thermometer works and at this point I am stuck at how to accurately adjust the weights on each globe to effect their temperature reading. Is there a formula for dealing with this? Or is the liquids in the globes different per globe and that is what makes them float or sink inside the main liquid and not the weight of the tag?
Any information would be appreciated.
