I used to use soda water to temporarily put Gammarus,a small 
crustacean, to sleep; I immersed them in it til they stopped 
twitching. I was told it was the CO2 that did it. Had to be careful 
not to overdo it and kill them, as I needed to recover them.

          As for lobster , I put them in the freezer for about 20 min or 
so til they hardly move , and then plunge them in boiling water 
head first. They supposedly die before waking up , so the theory 
goes. Makes me feel a little better and I don't lift the lid  :-).

               Lobster goes well with garlic and butter too,
