Hard to top this one! A gender reveal party in Arizona sparked a wildfire that caused a 47,000-acre wildfire. An off-duty Border Patrol shot at a target to announce the gender of the child he and his wife were expecting. The target had Tannerite which is described as a substance that explodes when hit with a bullet from a high-velocity firearm. The explosion started the fire that ended up causing $8 million of damage. This makes the old balloons in the box reveal seem not so lame!
