It is possible to cut the top off a alcohol-in-glass thermometer without any of the alcohol spilling out. However, it will no longer function as a good thermometer. Why not.
I am thinking it is a lost pressures issue.

It is now a barometer with the Mercury going up with low barometric pressure.
The alcohol would evaporate
Thank you so much.
It might last a few weeks in a bar, depending on the partial pressure of alcohol in the air... :)
