Tannerite is fun to shoot, but this is why you have to have to be extremely cautious. This stuff is dangerous.
A grizzly accident happened when 32-year-old David Pressley along with some friends put about three pounds of Tannerite into an old riding mower with the intent to shoot it and ignite the explosive.
Video shows a man identified as Pressley firing into the lawn mower with a semi-automatic rifle.
After getting what was described as "more than 20 shots" off, the lawnmower exploded.
Pressley can be heard yelling "I blew my leg off!" and blood spatters appear on him.
WARNING: The video is graphic in nature.
Editor's note: the article says the man was 32 years old, while the video states he is 23 years old.
While Tannerite is legal in the state of Georgia, the Walton County Sheriff's Office gets several complaints a week concerning the explosive. Sheriff Joe Chapman said in the video, "It's very dangerous, it's not a toy. It's much more than a firecracker."
Pressley's friends managed to fashion a tourniquet around the injured man's leg, help him into a vehicle, and drive him to a nearby road where he could be airlifted to the hospital. Pressley's left leg was missing below the knee.
While he is recovering from his injuries in Atlanta, there's no telling how many injuries occur from Tannerite use. Chapman said that a general rule-of-thumb was to be a hundred yards away for every pound of the explosive used.
Pressley was just over 40 feet away when the explosion occurred.
