Pressure-switch pads in each pocket are connected to a little trigger controller and speaker mounted on the billiard table. When I pocket a ball, it triggers the sound of bowling balls being flattened, applause, or Ed McMahon yelling "heeey-oh!". Sound themes easily switched using flash memory cards.-- gonzola, Jan 05 2009 Each ball has a sensor located with-in its core; when pocketed, the table will recognize which ball has entered. Visual effects like smoke or those lil party poppers/streamers would discharge.-- when you notice me not waving, Jan 05 2009 What is the sound of one bowling ball being flattened?-- Canuck, Jan 05 2009 random, halfbakery
