Immerse yourself in goo, gunk, and grit to create art and explore science. From water play and oobleck pools to foam parties and foot painting, there will be plenty of ooey, gooey, slimy messes to dive into. Activities will be outside and inside the museum, and we’ll wind up the day with a Rockstar Bubbles Foam Party! Dress for mess and bring a towel and change of clothes.
