Galileo Thermometer
I wouldn't take it as fact the temperatures that it gives you though I haven't actually tested how accurate this thing is. However it is a nice conversational piece. I had bought one while I was stationed in England and it was broken after I got to the US. So I decided to buy another one to replace it. I have also bought three more just like it. This is an awesome piece just to look at.

Attractive but not accurate
The Galileo Thermometer is a both a beautiful piece of artwork and a functional scientific instrument. The thermometer operates on the principle that the buoyancy of liquid decreases as it warms and expands, allowing the weighted glass spheres to descend one at a time.

The thermometer looked impressive when I first took it out of the box, but my excitement turned to disappointment when I tested it over the full temperature range. Several of the spheres are either severely miscalibrated or put into the tube in entirely the wrong order. This causes them to stick together and jam the tube. If you want to buy a poorly calibrated Galileo Thermometer, you can find one that is much smaller and much cheaper.

Great buy
I love it. Its great looking and is accurate. Plus it never runs out of batteries. My only problem was with shipping, it was a week and a half late.
