Galileo Thermometer Closeup

I posted a shot back on February 19 showing the whole thermometer if you want to see what it looks like. This is a working thermometer based on what Galileo built. There's a lot of YouTube stuff on how it works, so, basically, you read the temperature by looking at the tag on the glass ball floating in the center -- the blue one in this frame. You can't see the tag in this image but it's indicating the temperature is 70 degrees. (Knicknacks DSC_0229.jpg
