Chance the Rapper announced yesterday (July 6) that he would be surprising kids from his hometown of Chicago with field trips to some of the city’s museums.

Chance fulfilled his promise today (July 7) when he brought a group of children aged 6-11 to Chicago’s Field Museum. In an Instagram post, he leads the kids in chanting “Cole Park field trip” as they take a bus to the museum.

He also posted a picture with the children in front of “the largest T.Rex ever found,” according to the museum’s website. The kids are holding up papers featuring the rappers’ Social Experiment logo.
