Years ago you could buy ant communities trapped in sand inside glass. You could watch them scurry about hither and yon. Do they still exist?

Currently in America we are all ants trapped in sand in glass surrying about hither and yon. Very busy. Can't you see that? So important doing moving talking whatevering. Busy busy busy busy.

How long does a community of ants trapped in glass stay alive/survive? Lilterally?
