BOB breathing observation bubble

The Breathing Observation Bubble, or BOB, is an underwater scooter which eliminates the need to breath through an uncomfortable regulator by shrinking your nut to the size of a cabbage pumping an acrylic bubble full of that finger-lickin' good O2. Operation can be mastered in just "a few minutes" and can scoot along at a top speed of 2.5 knots under the power of a 35 pound thrust electric motor. We'd probably say this was kinda cool if only we could stop chortling to ourselves. The problem of what to do when you have to scratch your nose is still as yet unresolved.
