Thomas had a blast yesterday experimenting with the texture of just plain old corn starch and water! We picked up this book, Science Crafts for Kids: 50 Fantastic Things to Invent & Create (amazon affiliate link), from the library on our last visit. It has some really cool and fun stuff in it; but we only had the ingredients and items needed for this one experiment. I have no idea where the word oobleck came from . . . it’s what the book called this one . . .
