In the "Go Large or Go Home" category, I used the DIY Stir Plate to de-gas a carboy of mead. There is about a quarter-inch of glass on a carboy bottom; the key is to get as much magnetic field as close as possible to the stir bar. It took two stacks of eight rare-earth disk magnets to drive the stir bar. Spun it for several days in various places around the carboy bottom with no problems. The key seems to be to "capture" the stir bar (both ends) with the two magnets, then spin up the motor slowly. After the motor spins up, reduce power slightly so the stir bar doesn't get thrown off.
