I had bought some mylar balloons at the dollarama, but I tasted the air/CO2 after filling a balloon and it tasted a little plastic-y. After cutting out the valve in the balloon, I tried washing the inside so that I could sanitize it, but then the balloon ripped. So I figured a 10 l food grade plastic bag duct-taped to soke tubing would do the trick, and no need to sanitize!
I immediately replaced the blow-off tube with the new CO2 tube. The Sodasteam works awesome for filling it with CO2 - just a couple of pumps and it is full. I then checked that the setup is airtight by squeezing the bag... no leaks!
So it's now crashing in the garage (covered, in a bin so it doesn't get sun--struck), and I am monitoring the temp to make sure it doesn't freeze. Been real lucky with the mild weather so far!
I also monitor the CO2 level in the bag (it does go down over time), so I just pull off the hose, cap it immediately and top the bag up with the Sodastream.
