Send a Ball, the online store that lets you create personalized inflatable balls for any occasion, made its ABC Shark Tank debut tonight. Here's how the business started: "One day I [co-founder Michele) was in Osco, saw a BIN of bouncy balls, grabbed one and thought "I can mail this". Took a sharpie, addressed it to my BFF Sharon, wrote "Have BALL with your new baby", went to the post office and mailed it." More information. Video after the break.
