The opportunities for aspiring entrepreneurs hoping to launch a business are virtually limitless. A story from the Wall Street Journal this week reported a growing number of young entrepreneurs taking advantage of the popularity of beer pong, a drinking game prevalent on college campuses. While the game typically doesn't require much in terms of equipment, Northwestern University graduates Andy Wright and Mike Johnson started selling rubber mats designed to prevent cups from toppling over and spilling precious beer. But it doesn't stop there. The story described several other beer pong business ventures from current and former college students, including portable tables and apparel.

While at least a dozen universities across the country have prohibited these and other drinking-related products, the beer pong craze is still going strong. Billy Gaines and Duncan Carroll, grads from Carnegie Mellon University and the creators of bpong.com, hosted the first World Series of Beer Pong last year.--Kevin Manahan
