Corn starch
Water
Materials:
Bowl
Clean hands
Recipe:
1 Cup
cornstarch
1-2 Cups
water
Food
coloring if desired
In a bowl,
add your cornstarch. Slowly pour in 1 cup of water. Mix
together with your fingers until you have reached a
consistency that will act like the Non-Newtonian fluid
described. Add more water if necessary. If your Oobleck
is too watery, just let it sit for a while. The
cornstarch will eventually settle to the bottom. Take a
napkin or paper towel and dab it on the top of your
cornstarch+water mixture and it will soak up some of the
excess water. Mix together again. Add several drops of
desired food coloring. Once you have reached the desired
consistency, pour a bit of it out onto a flat surface.
You will see that it pours out as a liquid. Now the fun
begins!
Take a
finger and try to run it through the “pool” of Oobleck.
You will see that it crumbles. You can break it into
solid pieces and it will quickly change into a liquid.
Have fun!
