Corn flour and water also known as oobleck is very easy to make. The interesting thing about corn flour and water is when you mix them together you get a non Newtonian fluid.
It will resist sudden impacts. This means if you were to punch it, the fluid would turn solid like on impact, but at the same time you could pour it out of the bowl and it would have a consistency resembling thick golden syrup.
Now what you should have is a goo that is resistant to sudden force. You should be able to role it into a ball. Then stop applying pressure and watch it appear to melt back into a gooey puddle.
The slime will dry out when it is left out to long, which makes it easy to clean off. Keep it in an air tight container and it will last for about a week.
This slime makes great entertainment. You can fill a balloon with it and then use it as a stress ball. It also makes a fun activity for children’s birthday parties. While it is great fun there is a lot
of science behind why it behaves the way it does.
"What I'm trying to do with most of my work is establish this new modernism, ...
If people don't walk out of theatres saying,
'Yes, something is possible,' then you've failed."
The oobleck basically works by trapping water in the non-crystalline corn starch particles on impact and then they release that water once the pressure is gone this makes it feel solid. The corn flour doesn’t dissolve in the water it actually only stays suspended in the water so if you leave it for a while the corn flour will settle to the bottom. I found that with a little experiment of my own that if you cook corn flour and water it turns in to a gel it make such a great
thicker in sauce.
Do not pour it down the drain!
