(CNN) Oh boy. A video released by the US Forest Service shows the moment when a gender reveal party in Arizona went horribly wrong, sparking a wildfire that burned nearly 47,000 acres and caused more than $8 million in damage.

Shot on April 23, 2017, the clip shows a makeshift target with the words "Boy" and "Girl" written on it, placed in the middle of the desert near Green Valley, Arizona, south of Tucson.

Seconds later we hear a gunshot, and the target explodes, revealing a blue cloud and immediately igniting the surrounding brush. Someone shouts, "Start packing up!"

The flames spread to the nearby Coronado National Forest, where they became the Sawmill Fire and burned 46,991 acres owned by the state of Arizona, federal agencies and private landowners. Firefighters from at least 20 agencies fought the fire for about a week, according to CNN affiliate KGUN-TV

The man who shot the target, off-duty US Border Patrol agent Dennis Dickey, pleaded guilty in September of this year to a misdemeanor violation of US Forest Service regulations and was sentenced to five years' probation. He also was ordered to pay $8,188,069 in restitution , starting with an initial payment of $100,000 and monthly payments thereafter.
