Is it a solid? Is it a liquid?
Joseph and Libby have been sitting at the kitchen table for an hour investigating the properties of Oobleck (a very secret recipe involving cornstarch and water ;)). Joseph has decided that Oobleck will deserve an entire chapter in his book.
They are absolutely fascinated that a substance could exhibit the properties of both a solid and a liquid.
Caroline was grossed out really quickly and went to play on the computer.
The girls read Bartholomew and the Oobleck as part of their studies on Solids, Liquids and Gases.
