Switching from live to frozen/thawed. How?

[Slim]

No idea what cervical displacement is... but what I did was I put the mouse into a zip lock bag. I waited thinking it would just suffocate, but it didn't. So I took my tongs and pressed the mouse down so it couldn't breath in. The tongs were wide enough to extend from rear legs to front legs. It was dead literally within 4 seconds.

Please do a simple frickin' Google search for cervical displacement.

As for your method, I've literally been sitting in front of my screen for the last 5 mins trying to type a response. Words just fail me, but, don't do that anymore
