Las Vegas celebrated its 100th anniversary in May 2005 with the world's largest birthday cake. But what happened in Vegas actually started out at a Sara Lee bakery in North Carolina.
Before the party could start, 30,000 half-sheet cakes and 40,000 pounds of frosting traveled across the U.S. in eight semitrucks. It took 1,000 volunteers 14 hours to unload, assemble and frost the convention center-sized cake.
When it was finally ready to be cut, the Las Vegas centennial birthday cake stood 20 inches tall and was the size of an NBA basketball court -- plus an extra 8 feet in length. It weighed a staggering 130,000 pounds, or about the same as two tanks used during World War II.
