Other uses for CO2
« on: February 13, 2011, 08:04:22 AM »
This is slightly outside of the kegging and bottling category, but a different post had a story about using CO2 to cool down the costumes at Disney World...which got me to thinking.....since I have this monster bottle of CO2 now, what else besides kegging and brewing can I use this for?  Oh, and nothing dangerous.

I just would think it a shame if I couldn't find another use for it.

Still brewing related.
I ferment in carboys and use it to force rack to another carboy or keg. Eliminates lifting full carboys up to use gravity to rack.  My beer never sees oxygen. You must do this w/ caution because carboys are not designed for pressure. Be sure to purge the receiving vessel w/CO2. I use only enough pressure to get the beer moving( a lb or two, hardly even registers on the gauge) and it usually takes 10-15 mins for transfer. What's the rush?
You probably already have the equipment: 2 racking canes, tubing, carboy cap, and a barbed connector to connect the gas line to the carboy cap.

I use quick air disconnects with the male end on the tank side so it has a nice tappered finish for using with hoses and carboy caps for pressurizing for transferring.



This allows me to switch between my keg setup, a single ball lock connection for carbonating other kegs, double ball lock connection for carbing up two kegs and my beer gun fittings.

So far I haven't had any issues with any noticeable leaking, though I add a little keg lube to the disconnect to help seal it

Make sparkling water.

Or tonic water: http://www.jeffreymorgenthaler.com/2008/how-to-make-your-own-tonic-water/

Or better yet, pre-carbonated Gin and Tonic.

Actually, I've been thinking about adding a fitting to my pressure cooker to allow me to cook under pressure at a lower temp.  And fool around with cooking food in a low O2 environment.

I think I may make sparkling water and try something like rootbeer, just because I can....but I am looking for the ultra weird, would have never thought of THAT! Eureka! type use.

champagne.

I've one of those grow domes to raise tomato plant seedlings. Been trying to figure out how to run a blow-off line from the fementer/freezer to the grow dome.

Fill one ballon full of it at a kids b-day party and let them rack their brains over why one ballon falls faster than all the rest.

and then watch them pass out when they keep trying!

I did this with my son using baking soda and vinegar.  I was even amazed at how heavy the co2 balloon felt.  I knew it would be heavier than the air filled one, but it actually felt "heavy".

Yeah.  Also, If you notice, it only falls faster for a few inces until they both reach their termnal velocity.
