I remember when I was about 15 years old, a guy (either a doctor or
engineer) came to my school and demonstrated this to my class. I still
remember it very clearly. He first used a bit of chloroform or ether to
'knock out' the mouse then put him into the beaker of fluid. We watched
the mouse breathe under the fluid for a while. When the mouse was pulled
out the guy said 'time for a bit of mouth-to-mouse resuscitation' and blew
into the mouse's nose to help clear the fluid out of the mouse's lungs.
(All the girls were suitably disgusted by this step!) After a minute the
mouse was running around again and seemed no worse off.
