That reminds me of brewing at my parents place when I was 19. I had a large white plastic carboy that I pitched the yeast into and and put the airlock on.
Yeast selection was limited back then (to say the least) and I don't remember if it was a different strain or what, but it sure took off! Hops clogged the airlock, pressure built up...
I was at the bar and when I came home there was a nasty note. I went downstairs. There was a beery stain in the ceiling and a hose in the bung.
My Mom told me it sounded like a gunshot. The airlock launched at high speed and hit the ceiling. My Mom and my bro (15 at the time) ran downstairs to see a beer volcano spewing hops and beer onto the ceiling like a crazed fountain.
Wish I could have at least seen it. When I asked them if they at least took pictures, they didn't find the question as amusing as I did.
