ISI Whip Question [moved from General Topics]
I have an older ISI whip (10 year old probably) and it only came with a blue canister holder that you use to physically push the canister into the cap to discharge the gas. My seltzer bottle has the screw on cap.
So there is the possibility that you can just wrap the cartridge in a kitchen towel and press it into the canister. I do hand hold on my cartridges to discharge on my whipper - I have no idea if the canister designs have changes/etc. But it is how it used to be done on older models.
