Lucas John "Luke" Helder (born May 5, 1981) is a former University of Wisconsin–Stout college student from Pine Island, Minnesota, who earned notoriety as the Midwest Pipe Bomber in May 2002.
While attending the University of Wisconsin–Stout and living in an apartment in Menomonie, Wisconsin, Helder planned to plant pipe bombs in mailboxes across the United States to create a smiley face shape on the United States map. The bombs, which were packed with BBs and nails, were rigged to explode as the mailboxes were opened. Completed and rigged bombs were found in Nebraska, Colorado, Texas, Illinois and Iowa. In Iowa, six people, including four mail carriers, were injured when the bombs detonated. Ultimately, Helder planted 18 bombs and covered 3,200 miles. He was eventually captured in rural Nevada before he managed to complete the full smile. At the time of his arrest, police were looking for an unknown suspect driving a black Honda Accord and newspapers reported that he was wearing a Kurt Cobain T-shirt. The bombings were heavily covered by the United States media.
In April 2004, a federal judge found Helder incompetent to stand trial. While the judge could free Helder if doctors find he is not a threat to society, legal experts doubt this possibility due to the violent nature of his crimes. He has been diagnosed with schizoaffective disorder and remains incarcerated in the Federal Medical Center in Rochester, Minnesota.

(1) Two liter bottle of chlorine (must contain sodium hypochlorite)
Small amount of sugar
Small amount of water
Mix all three of these in equal amounts to fill about 1/10 of the bottle. Screw on the lid and place in a mailbox. It's hard to
believe that such a small explosion will literally rip the mailbox in half and send it 20 feet into the air!
