FUNNY SCIENCE-Make your own Chemical Creature
Poziom:
Temat: Nauka i technologia
On this week's episode of Scientific Tuesdays
we're going to be creating a non-Newtonian fluid
Now, what that means is basically any fluid
that does not follow the laws of physics.
So water is an example of a Newtonian fluid
because it follows all those rules.
When you pour it out it pours out.
When you stir it stirs.
Now, we're going to make something out of corn starch and water.
And I'll show you exactly what I mean by non-Newtonian.
Do this at at home.
You're going to need a measuring cup,
a bowl
and a glass of water.
Now, most importantly, you need 100% corn starch.
You can get this at any supermarket
or you might be able to find it in your pantry already.
Get your corn starch and pour about a half a cup in.
This is a good amount to, sort of,
see how this stuff works and mess around it for yourself.
Once you've had the half of cup ready,
pour it into your bowl.
The next step is to add water.
Now, we're going to have a quarter of a cup to this.
Basically, 2 parts corn starch and 1 part water.
Once your mixture is complete, stir around a little bit with a fork or spoon.
Make it slow, make it sure the substance is thickening.
Make sure it looks like this a little bit.
You need to test to make sure it's ready.
So, once you've done stirring
reach it and grab it and roll it around in your fingers a little bit.
If you can keep it solid while you're rolling it
then you're ready.
As soon as you go of it, it should turn back into a liquid.
To see some of the cooler effects to this
we going to pour it into a speaker that is water-sealed.
If we play a high enough frequency sound
the liquid will take on a mind of its own.
When the pressure is applied
the substance thickens and it begins to grow.
Go over the place.
