Four milk jugs filled with gasoline were wrapped in detonation cord outside a Las Vegas Fire Department training center on Wednesday.
Bomb squad technician Mark Duncan yelled, “Fire in the hole!” three times.
A loud bang sent a fireball about 10 feet into the air of the eastern valley and a large plume of black smoke even higher into the clear desert sky. Duncan said the explosive weight of the blast, part of a media demonstration, was the equivalent 0.11 pounds of TNT.
