On Saturday and Sunday, August 10 & 11, attendees of the Maryland Science Center’s annual Mess Fest embraced the chaos of creativity, donning paint clothes and dirty sneakers for a day of messy, interactive fun. The celebration, known for its embrace of mucky, slimy, and sticky science, featured a range of activities. Participants engaged in paint-splattering catapult challenges, dove their hands into pools of goopy oobleck, created spin art on specially designed bikes, and left their artistic impressions on the Science Center’s windows.
