We made whipped cream for our apple pie last week, but for some reason, the second time we tried to use it, nothing came out. Not any whipped cream, not any nitrous oxide, just nothing. So we (mistakenly) thought that maybe the canister had somehow de-pressurized...because we knew there had to be whipped cream left in there. So Chris decided to very cautiously open the canister in the sink, just in case it exploded.
Well, it exploded. EVERYWHERE. And opening it in the sink did. not. help.
If you can't see from this picture, it launched all over the walls, behind Chris's back all the way to the pantry door and the oven behind him. And on the floor. It wasn't pretty.
