It’s not every day you get to see a movie with tennis legend Serena Williams, but for a group of future scientists and engineers, that’s just what happened.

Last night, the 23-time grand slam champion, surprised a group of young girls from Black Girls Code to a surprise private screening of Black Panther. 

Williams wrote on Instagram on Friday, “Last night we surprised a group of girls from @blackgirlscode to watch black panther with me in a private screening.”

From the looks on their faces, they seemed to enjoy visiting Wakanda.

Black Girls Code is an organization that’s committed to getting young girls of color into computer science and technology fields.
