Every October, we hand-pick a collection of Science Buddies projects and activities that tie in with all things Halloween. This year, we have even more great suggestions for slimy, icky, ghoulish, spooky, gross, or tasty hands-on science for Trick-or-Treat week and beyond. We can help you light up your costume with science, too!
