Jonas Brothers star Nick Jonas has been mastering the art of the plastic Wiffle ball throw in his spare time and can hurl it at up to 73 miles-per-hour.

The teenager decided to perfect his throw after failing to hit the target during a charity event on U.S. TV show Ellen - and he quickly went from accuracy to velocity. He says, "I went into training...I can get the ball up to 73 miles per hour."

His determination has impressed his bandmate brothers. Joe Jonas explains, "It's so fast... He could seriously injure someone. It is amazing, it's unreal."

Jonas showed off his Wiffle ball skills during a return appearance on Ellen, which aired on Tuesday (17Feb09). (KL/WNVELL/AV)
