Couldn't you use one of those Seltzer Syphons (those things you use to make home made seltzer) and run the tube from the head portion into a semi air tight container (I'm thinking cheap gladware with a few holes in the top) containing the mice? CO2 is heavier than air, right? So a few blasts should displace all the breathable air in the container, and with outflow holes the overpressure wouldn't be that great (I'd think). I should just go look at the instructions on Jay's forum...
