Rat breeding Q's

Do you possibly have a picture of the tubing connected to the end of the CO2 chamber? Does it fit snugly or did you have to wrap tape or somethign around it too?

looks like a great idea. I think for now dry ice is the way for me. It's fast to get and not another device I have to keep around. Plus I can still use the ice box. I'd have to go out and get a hose to go from the tank to the container. Maybe in the future I'll be making one, just not yet.

I used hot glue for both tube connections, they should be airtight. Silicone would work as well, or even tape in a pinch if its reasonably airtight.

The exhaust hose goes in a glass of water so it will release exhaust gas/air but not allow oxygen back into the chamber.
