Logansport Library’s “Young Scientists” discovered a substance that can change from  a solid to a liquid and back to a solid without changing temperature. 

The 3 States of Matter are: 1. Solid  2. Liquid  3. Gas.  Usually, to change a substance from solid to liquid or liquid to solid the temperature of the substance must change.  OOBLECK does not follow that rule.  It can be both a solid and a liquid at the same time.

Recently the “Young Scientists” at the Logansport branch library enjoyed making their own OOBLECK.  It was exciting to experiment to find out what makes it change from a solid to a liquid.

According to Instructables Workshop (Instructables.com) on the internet, 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. On the site the Oobleck will be made in a bowl and will likely make a mess, but only because you can get carried away playing with it.

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!
