EY 2 students made a kind of play-dough created by their own. Oobleck is a suspension of cornstarch and water that can behave like a solid or a liquid depending on how much pressure you apply. Try to grab some in your hand, and it will form a solid ball in your palm until you release the pressure. Then, it will flow out between your fingers. Everybody didn’t want to stop playing it. What a messy class.
