SHOCKING video captured the moment a floor collapsed into the basement during a house party attended by at least 150 guests.
The floor gave way during an out-of-control birthday party at a home in Arapahoe County, Colorado, 44 miles from Denver, on Saturday.
The homeowners say they were hosting a birthday party for their 18-year-old grandson when a portion of the first floor collapsed into the basement.
The madness escalated after word reportedly got out on social media, where the address was shared, and people began showing up in droves.
“I think it just got leaked around a little bit so everyone thought it was just an open house. People started just showing up,” attendee Cass Henry, 15, told KUSA.
According to officials, around 100-150 partygoers attended the birthday bash.
Officials said three revelers were taken to the hospital, one in serious condition, and the other two suffered minor injuries.
Henry said he and his brother, 17-year-old AJ, were among the partygoers who fell through the floor.

“Two seconds before the ground ended up breaking, you could hear it all snapping apart, but you didn’t have enough time to do anything about it,” Henry said, who suffered a broken ankle.
The collapse caused a brief natural gas leak that first responders shut off.
Scott Richardson, special operations chief for SMFR, said it was "amazing that no one was seriously hurt or killed."
“It’s not the static weight of us just standing on [the floor], but if people are jumping up and down, and that creates what we call a ‘shock load’ to the floor, and then you can’t really predict what’s going to happen.”
