SARGENT, TX (KTRK) -- A teenage boy is spending July 4th in a hospital bed, after a weekend fireworks encounter went very, very wrong.Rowdy Radford, 15, lost several fingers and part of his leg and may lose his sight after the fireworks accident Saturday night in Sargent, Texas. His mother wants his story to serve as a warning to other parents to keep a close watch over their children.At about 11:30pm Saturday, Rowdy was playing with fireworks, according to his mother, when he decided to tape together more than 100 sparklers. As he went down to light them, the wind caught the flame and the bundle blew up on Rowdy.The teen was taken by Life Flight to Children's Memorial Hermann Hospital, where he has undergone multiple surgeries. His injuries are extensive, and his mother, Wendy Smith, says doctors are not yet sure if Rowdy will ever see again.Smith said her son is known for building his loud "sparkler bombs." Through tears, she described how Rowdy built his sparkler bomb Saturday night."He went to the fire stand and bought forty dollars worth of sparklers," Smith said.Smith said her son wrapped them all together using duct tape. Rowdy's aunt, Samantha Hansen, explained her nephew's technique."He takes the sparklers and has one stick out of the center, and he uses that sparkler as the fuse," Hansen said, "And once it gets down to the other ones, that's when it goes 'boom.'"Smith was inside when the bomb went off around 11:30 Saturday night."Then I hear people screaming, saying, 'Your son got hurt,' Smith said, "Then after that, I don't remember. I blacked out."Family members called 911 and Life Flight flew Rowdy from Sargent to Children's Memorial Hermann Hospital in Houston's medical center. Rowdy had his left leg amputated below the knee. He is sedated, in critical condition."Hopefully he'll get his eyesight back because they couldn't get in there and clean them," Smith said, "He has wires, sparkler wires in his eyes."As families across the state and country prepare to light fireworks tonight, Smith urges them to rethink their plans."I pray and hope they don't do it," Smith said, "Because I don't want them to go through the same pain that Rowdy's going through."*Obey all local laws regarding the use of fireworks.*Know your fireworks; read the cautionary labels and performance descriptions before igniting.*A responsible adult SHOULD supervise all firework activities.
