8 Foot Galileo thermometer in action

Using the balls from a broken Galileo thermometer I built an 8-ft. tall version and hung it outside my sunroom window. The top ball sinks at 45ºF and the bottom ball floats at 10ºF.

Well I found my Galileo thermometer broken after moving. I love this reincarnation rather than throwing it away.

What was used for a tube? for the liquid?

The tube is an 8 ft. polycarbonate (Lexan) tube that is sold to protect 8 foot fluorescent light tubes. The liquid is naptha. Both can be found in most hardware stores. You might have to recalibrate to have the spheres work correctly.

This has got to be the worst video I have ever seen. Were you trying to make it bad?

OK, sounds great.

I picked up the Lexan tube and gallon of naptha. I think I might need more though. A 4 foot by 3 inch tube might be more like a gallon and a half!

I have a question about how you calibrated the spheres. Did you just grind the tags? What were the calibration steps?

Nice job!
