To promote an upcoming Super Bowl ad, Mars Wrigley unveiled the largest Snickers ever made, a 4,728-pound confection.

The bar revealed on Thursday morning at the Mars Wrigley plant in Waco, Texas is more than 1,200 pounds of caramel, nougat and peanuts and 3,500 pounds of chocolate. The Waco plant opened in 1976 and has some 600 employees who make 65 percent of all the Snickers sold in North America, 80 percent of the Skittles and 100 percent of all the Starburst, according to a report from KWTX.

The New Jersey-based company used the event to tease to an ad that will run during the Super Bowl on Sunday, Feb. 2.
