I am informed that the best place for floating an air biscuit is on an escalator, either ascending or descending - as your audience comes to you directly.
The champions of course were Paul Boomer and Lord Windesmear: in the long-time classic match "The Crepitation Contest." (it's long 15 min., so stay with it)
For people like me who "like their own brand" I heartily recommended letting one go in the shower. Turns any shower into the old San Quentin death chamber.
