Hey everyone, just wanted to show a alternative method I have been using for my rats. A lot of people like myself don't have access to refill large containers of CO2 nearby, hopefully this helps!

I get a pack of CO2 from Walmart which costs me about $8. The picture shows the pack, one out of the pack, and the little unit I came up with. It's just some stock that I had laying around and gave it a shot, it has been working perfect !



This is the top, drilled some holes to let the CO2 out



I placed a short nail into the center to puncture the top of the CO2



Here is the stock with the threads



CO2 cartridge how it fits inside



Placed inside



Top back on with CO2 placed inside




I just turn the top slowly until I hear the CO2 start to release and I place it in a shoe box size tub.

Thanks a lot for checking it out
