I have one of these too. I use it to show what happens as a material heats
up. Increases molecular vibration, expansion. Don't know if that was its
original use but that's all I could come up with.

Subject: Weird mercury tube

Greetings,

We're moving into a new building, which entails plowing through piles
of weird objects in the demo room that haven't been disturbed for
decades. One item in particular has everyone puzzled. It's a sealed
glass tube with a few cc's of mercury and some bluish-purple
crystals. The tube is supported in a heat-resistant clamp, so I
presume it was once heated. Anybody have any ideas about what it
might be good for, or should I consign it for hazardous waste
disposal? Thanks.
