Today in Science, we played with OOBLECK. It is a really weird substance made from cornstartch and water. It is really goopey and fun to play with. lf you handle it slowly, it portrays the property of a liquid. If you are harsh with it (punch or slap it), it portrays the properties of a solid.
We decided to colour it green with food colouring. It sounded like such a good idea, until we had to wash our hands. They ended up staining green from the dye!
I wasn’t sure what to classify OOBLECK as. Is it a solid or a liquid? After some research I found out that scientists classify it as a discrepant substance, meaning that it can change characteristics when a different amount of pressure or tempurature is applied.
OOBLECK reminded me of Silly Putty. Silly Putty did sort of the same thing (after a while it would melt like a liquid), but it would take much longer.
