It’s Wednesday. Let’s Get MESSY!

Who here LOVES to make slime?
Well, say hello to Slime's rebel cousin, OOBLECK!
First introduced in a Dr. Seuss book, Oobleck is a non-Newtonian fluid.
It doesn't follow Newton's law of fluids having constant viscosity.
Viscosity is how fast or slow a liquid moves.
But Oobleck is a shape-shifter.
Sometimes, it's a liquid and sometimes, it's a solid.
It all depends on how much pressure is applied to the substance.
Here's more of the science behind it.
Long story short, Oobleck is complicated yet super easy to make!
All you need is water, cornstarch (any powdered starch works), a big container and if you're feeling adventurous, some food coloring.
Step 1
Put 2 cups of cornstarch into a container.
If you don't have a measuring cup handy, any ordinary glass will do.
Step 2
Add 1 cup of water.
Use the same glass. This ensures an accurate 2:1 ratio of the ingredients.
Step 3 (Optional)
Add some food coloring.
A couple of drops should do it.
Step 4
Mix it up!
Get your hands dirty and knead the mixture until everything looks the same.
Step 5
Experiment!
- Squeeze it into a ball. Then, open your hands. Does it "melt" right away?
- Test out different utensils. Try an ice cream scooper or a dough roller. What's the reaction?
- Gently swish the container. How fast or slow does the oobleck slosh around?
- Poke at it. Does your finger sink in or bounce back?
What the Heck? It's OOBLECK!
Had enough fun for one day?
Let the oobleck dry out and simply add some water when ready to play again.
You can even throw in some UV paint and turn it into a Halloween trick.
Done for good? Then, it's time to clean up.
Avoid a clogged drain and just throw it out in the trash. Easy peasy.
And don't forget to spread the joy if you made the most out of your messy crafternoon.

You know the drill.
Check back in next week for more awesomeness!
