You can safely let the air in (or vacuum out) of a CRT by breaking the
"tit" on the back end of the CRT where the air was evacuated. It may be
covered by the plug for the electrical connections. If it is then just
break the plug off. The glass is very thin there and I've seen may people
just use a karate chop motion with almost any metal object to break the end
of the tit off. That will let the air in and the rest of the tube stays
intact.

I am NOT RESPONSIBLE for any injury caused by trying the above, BTW!!!
Modern CRTs can't violently implode, but it's still wise to take care.
I have included the caveat in the quote for obvious reasons. A master
at my old school used to break up old CRTs by _gently_ tapping at the
base of the neck with the ball of a hammer. This created a small hole
to release the vacuum.
It looked dangerous to me so I used the 'blanket and brick' approach as
in (c) above or put the tube in a dustbin and crouched down beside the
bin and used a hammer to knock off the neck keeping the bin between me
and the CRT.
