Hi folks,
Does anyone here have experience of getting the air out of a mercury
barometer column?
The standard procedure is to turn it upside down, use an eyedropper to
fill the bottom of the tube, and poke a wire down the column to knock any
air bubbles loose. Then, the TRICKY part is to get the tube back right-
side-up without allowing the mercury to escape and air to get back in.
It seems impossible to do this without getting your hands in the mercury.

I think nitrile gloves will work just fine to keep mercury from
touching your skin. As long as it is not methyl mercury. A drop on a
rubber glove will still kill you. Slowly. Like in a few weeks.
