500,000 plastic orbs + adult beverages + tons of tunes = The Festival of Balls.

Did someone say balls? Heck yeah, they did! Coming to Denver on September 14: The Festival of Balls Ball Pit Party! You read that right, this fall, dive into the pit, play around with thousands of balls, and have a grand time that's a throwback to childhood. 

The Festival of Balls is gracing us with its pit party, complete with balls for days in the adult-only 500,000-ball pit and playground.

"Ball Pit Party is an adult wonderland combining the playground filled with balls and our awesome bar serving your favorite cocktails alongside top DJs spinning tunes all day!" says the event's Facebook page.

This pop-up (which appears to be affiliated with The Brick Bar, coming to Denver June 7-9) rolls to us from Australia, where the ball pit bar originated, and will also be visiting other U.S. cities, including L.A., Houston, and New York. If you aren't feeling the giant pit of people and balls, there are also plenty of other activities to enjoy, including pinball and a giant Connect Four. 

If you want to be a baller, you'll be given a time slot in which to play with all the balls you can handle. 

"Tickets are sold on 2-hour slots to play in the ball pit and dance with the tunes. A cash bar will be available with cocktails and more on show!" says Ball Pit Party. 

This is a one-day-only event, and the tickets are "extremely" limited, according to the Facebook event. Tickets are not on sale for the Denver date yet, but you can sign up for pre-release tickets at ballpitparty.com.
