Why should you never touch Mercury?

It’s never safe to touch mercury. Mercury is the only metal that is liquid at room temperature. In its liquid metal form, mercury absorbs instantly into the skin; but it also has an extremely high vapor pressure, so an open container of mercury disperses the metal into the air.

How do you know if mercury is real?

To test for the various forms of mercury, more than one type of sample may be collected and tested.
