David Slick had only one word to say when asked how his world record attempt went Sunday.
The 22-year-old Dallas Baptist University student juggled three tennis balls for 12 hours, 12 minutes and 12 seconds to break the previous record of 11 hours and four minutes in the "Juggling Three Objects Nonstop" category of the Guinness World Records.
"I knew I could do it. I knew it would be hard. But I knew it would be worth it," he said.
Slick said he knew it was possible because he'd already attempted the feat in his dorm room.
"You wouldn't believe how sore you could get just throwing some tennis balls up in the air," he said.
