I remember a cool toy that I guess wasn't a toy but it was glass and had color liquid in it and you wrap your hand around the bottom of it and the heat made the color bubble and rise. I never could figure out what it was called. Looking for the wheel-o reminded me of this.
Quoting: Anonymous Coward 27543704 Galileo thermometer is similar [ link to en.wikipedia.org] also the drinking bird. Found it, is called a hand boiler. I forgot it boils, thanks Seer. [ link to en.wikipedia.org] Those are neat thermometers.  Awesome recall. A hand boiler or love meter is a glass sculpture used as an experimental tool to demonstrate Charles's Law and vapour-liquid equilibrium or as a collector's item to measure love.
It consists of a lower bulb containing a volatile liquid and a mixture of gases that is connected usually by a twisting glass tube that connects to an upper or "receiving" glass bulb. [ link to www.youtube.com]  Nice. I think I had a red one.
