Oobleck is a delightful non-Newtonian fluid that exists as a liquid under low-stress situations, but becomes more viscous when agitated or vibrated. Named after a fictional green precipitation in a Dr. Seuss book, the substance is fun on its own, but you can add more awesome by making it glow (with highlighter dye, under a black light) and making it perform (by placing it on a speaker). Be amazed as it comes to life!
