Time-lapse video shows Levi's Stadium turning to ice

The San Francisco 49ers are upholding a basic tenet of playground etiquette: Sharing is caring. This weekend the San Jose Sharks take over the Niners new stadium in Santa Clara and take on the LA Kings. Ticket sales are skyrocketing; more than 70,000 hockey fans are expected to attend the game. This begs the obvious question: How does a football stadium transform into an ice ink? Thanks to the NHL, we can witness 200 workers make it happen in a minute and a half. Go Sharks!
