t’s time for the third annual Maryland Science Center Mess Fest! And you know what that means? Find some old clothes—this year is going to be our messiest one yet! Run, slip, and slide though our slop-stacle course, race different sticky slimes down three stories, witness a mega-messy explosion, and much more! Festivities will take place inside and outside (weather depending), and the event will go on rain or shine. Be prepared for a day of ooey-gooey, gloppy-sloppy, slimy science activities! All activities are free with paid admission and completely free for members.
