my mom is a chemistry teacher and found a glass tube containing mercury and blue crystals, what is it?
its less than a foot long and completely sealed in glass with one end pointed. it has mercury and some weird fragments of what looks like a blue crystal but it could be gel. i have no idea what it is but my mom found it in the chemistry class she teaches and was supposed to get rid of it because it contained mercury.
Maybe an old delay timer??? Hard to tell without seeing it but very old computers used to have mercury and quartz delays using a glass tube with quartz crystals and mercury...
