Brewing trivia:
The "parachute" referred to by Mark is item "B" in this 200 year old diagram. Excess krausen is skimmed and runs down into the parachute to be collected or re-injected into the wort.
When the modern escape-from-a-plane device was invented they needed a name for it, and presumably one of the original inventors had a brewery in the family and said "hey this looks like an upside down parachute".
