In this adorbs video, which will make you want to be 5 years old all over again, scientist and perennial Sesame Street denizen Grover (the thinking man's Elmo) wants to bring back dinosaurs. Unfortunately, science isn't exactly on his side. Fortunately, the 5facts gang steps in and shows Grover five science experiments he can do, with common household objects. He tests flotation, surface tension, density, chemical reactions, and my favorite, non-Newtonian solids! Even another grumpy Sesame Street guest star is won over.
