this is the first time I tried to make homemade whipped cream, so I bought a new whipped cream siphon and some N2O cartridges, and the first time I tried to use it, all worked well and I made a bit of whipped cream. When I unscrewed the canister cover though (the one the canister goes in to be screwed onto the bottle), I found that it was stuck inside and it took me about 15 minutes to get out with pliers. (Note: It also took a surprising amount of force to screw in in the first place)
I looked up some videos on how to make whipped cream, and they show people just shaking the canister out of the cover once they're done. There's no way I can do this, as when I insert it into the cover and just slightly press it in with my thumb, it takes a lot of shaking to get out. It simply gets stuck there almost immediately.
Do I have the wrong type of cartridge, or is there a step I am missing?
Thanks in advance!
