My aero bed has a big air leak in the mattress, so I'm essentially left with an air pump. Any suggestions on what to do with it?? Particular attention will be paid to suggestions that are: 1. Doable for a scrappy DIYer who lives 1/2 miles from an Ace Hardware. 2. Intended to keep said scrappy DIYer's 5-year-old son engaged, occupied and otherwise out of my hair for hours at a time.
