Just the thing for birthday parties, PTA fundraisers, Boy, Girl, Cub, and Daisy Scouting functions, and great for afterschool programs. They teach real scientific principles through a fun, safe, and exciting curriculum that allows for lots of hands-on play/work. My kids LOVE Mad Science, and they never run out of new courses. The instructors are wonderful, and very safety conscious and friendly. We just can't rave enough bout them.
