LeBron James and Bubblicious have started a league dedicated to the “sport” of bubble gum blowing.

To participate, you just go online to http://www.theultimatebubble.com to form a league with up to 10 of your friends. Then you compete to blow the largest bubble, the most bubbles in a minute and other events. You can keep track of the results online, and even compete in regional events.

The site has bubble-blowing tips, a bubble measuring chart and complete league rules.
