They'll try to breaking the world record for most people wearing sweatbands in one gathering.
From the stands, fans will pull on stretchy souvenir headwear inspired by the "Stranger Things" retro wardrobe and try to make their way into Guinness record glory.
With room for 10,000 fans at Durham Bulls Athletic Park, fans could easily pass the current record of 4,673 people, set in Louisville, Ky., in 2014.

The counting, of course, will be meticulous.
"Basically, there's going to be people all over the stadium whose job it is to count and help verify," said Bulls spokesman Matt Sutor. "And Guinness sends an adjudicator."
The "Stranger Things" series follows a team of "Dungeons & Dragons"-loving pre-teens after their friend disappears from their small Indiana town, which is situated near a mysterious research laboratory with a supernatural secret.
Dripping with '80s movies references, it sprung from the creative minds of Matt and Ross Duffer, who grew up on a tobacco farm outside Duke Forest in Durham. There have been two seasons so far with Season 3 in the works.
The series, though set in the fictional town of Hawkins, is also riddled with connections to local landmarks, from Jordan Lake and the Eno River to Mr. McCorkle, named for the Duffer brothers' neighbor. The brothers would have filmed in North Carolina, they said, if not for more attractive tax incentives in Atlanta.
The headband attempt is just one component of "Stranger Things" night, which incorporates multiple levels of fandom into the game against the Charlotte Knights.
Most noticeably, the Bulls will dress in uniforms inspired by the character of Dustin Henderson, one of the teens, including the iconic tri-colored trucker hat and blue backpack.
The world-record attempt is a joint effort between the Bulls and Relay, a Raleigh-based company that has created walkie-talkie-like devices with national reach. It is billed as a screen-free alternative to smartphones for kids.
Relay will provide roughly 7,000 pieces of headwear for the record try, which will come at the end of the third inning.
Increasingly, Guinness sets up corporate events aimed at building publicity through record attempts. In 2014, Nexen Energy set the mark for most people dressed at Batman, gaining headlines worldwide.
Meanwhile, in Durham, Belgian waffles, the favorite snack of the "Stranger Things" Eleven character, will be sold as concessions. Also, Christmas lights will be strung throughout the park, which series fans will recognize and others will have to investigate on their own.
