We heard the story of the King who wanted something new to fall from the sky.  So he asked his royal magicians for help and they create "oobleck", a green substance that rains down.  It is a gooey, gloppy green mess!  We experimented with this substance and it was fun! A quick tap on the surface of oobleck will make it feel hard, because it forces the cornstarch particles together. As you play with it, the oobleck becomes soft and liquid like.  Is it a sold or a liquid or a squalid?
