Mercury is a popular choice for thermometers.

Explanation:

Mercury's liquid form, its metallic and opaque character which make it easy to see through glass, and its uniform expansion with temperature are all assets for use in thermometers. But mercury is toxic, so be careful handling mercury thermometers to prevent them from breaking.
