Senior Airman Gregg Lowry, left, and Airman Kyle Irr, both 436th Civil Engineer Squadron explosive ordnance disposal technicians, string detonation cord around a ‘Boot Banger’, which are typically used to open vehicles’ trunks on vehicles April 5, 2012, at the EOD range on Dover Air Force Base, Del. The detonation cord is filled with condensed explosive powder, which burns at 23,000 feet per second. Since water is incompressible, it shoots the water at high speeds, making these types of detonations useful for disarming explosives. (U.S. Air Force photo/Senior Airman Jacob Morgan)
