"Oobleck is a non-newtonian fluid. That is, it acts like a liquid when being poured, but like a solid when a force is acting on it. You can grab it and then it will ooze out of your hands. Make enough Oobleck and you can even walk on it"!
"Oobleck gets its name from the Dr. Seuss book Bartholomew and the Oobleck where a gooey green substance, Oobleck, fell from the sky and wreaked havoc in the kingdom".
2 cups corn starch
1 cup water
food colouring (optional)
MIX EVERYTHING TOGETHER IN A BOWL....THEN PLAY
This stuff is great cause it washes off easily with water and is non toxic for curious little tasters!!
