How To Make Oobleck

The other day while we were making DIY Wallpaper Paste, the youngest decided she wanted to do an “experiment”.  With the cornstarch already out, I suggested we make Oobleck. 

Oobleck is a gooey, solid-liquid type substance that was apparently named after the Dr. Suess book “Bartholomew and the Oobleck“.  It’s a non-Newtonian fluid, which means that under pressure it acts like a solid, but when you release the pressure, it acts more like a liquid.

So here’s how to make it:

It’s so much fun!  Check out the video below of the Oobleck we made.  We mixed the food colouring in AFTER combining the water and cornstarch, which is why there are flecks of unmixed colour.
