I just found a keg of beer and tested it, it took a bunch of tries to empty it, but then it just reappeared as a keg of beer.
Ketchum, if you keep drinking, and then it is suddenly empty after a while, that means the code is working as it should.
For myself, I tried it with a beer keg, first drink I took emptied it. So you guys should probably do more thorough testing.
