WATCH: New video shows exact moment a gender reveal party started a 47,000 acre wildfire

Stills from a video of a gender reveal stunt that caused a massive wildfire

Fire, much unlike gender, is a binary. It’s either lit or it’s not.

And a new video of that 2017 gender reveal debacle that ignited a 47,000 acre wildfire in Arizona shows just how quickly that switch can be flipped.

The U.S. Forest Service released the 49-second clip this week, recorded on state land in the Santa Rita Mountain foothills.

Border Patrol Agent Dennis Dickey has admitted to starting the fire when he set off an explosion as part of a gender reveal party.

After the stunt ignites the grassland, a male voice can be heard in the video saying “Start packing up!” twice.

The blaze cost $8.2 million to put out, with nearly 800 firefighters on the scene.
