halfords, it was about 11 quid for the gas bottle, and 11 quid for the valve, the valve is reusable, but the cylinder isnt, but believe me, it lasts a LONG time

ye, you have to start by getting roughly 8% of the air in the tub as c02. you have to judge it crefully, 4 seconds on slow is normally ok, but just watch the mouse behaviour, you will be able to tell, once they have "fallen asleep" leave it for about 15 seconds, and then pump in the co2. i would say 5 seconds with the tap on medium/fast is ok. then leave for about 2 minutes observing to make sure that none of the mice are breathing, atall. then straight in the freezer, or to the snakes they go.
p.s make sure you put some sort of substrate in their, they empty their bladders when they die, so it does get messy.
