A goo and slime-based event for kids is coming to Orlando Science Center this weekend.

The Mess Fest takes place on Saturday, May 14 and Sunday, May 15 from 11 a.m. to 4 p.m. at the center, which is located at 777 E Princeton Street in Orlando.

The event will include slime and goo-based activities for children, with a host of “mess zones” to learn the chemistry behind the experiments to make slime. In addition to making custom slime, the event will also include colorful and sensory-friendly activities, according to event organizers.

WeFlip Entertainment will also perform a series of high energy acrobatic shows throughout the weekend.

Members of the Orlando Science Center may attend the event for free. The cost to attend for non-members is $21 for adults, $19 for seniors and students, and $15 for children between the ages of 2 and 11. Tickets include access to all four floors of exhibits, giant-screen and 3D educational films, and live programming.
