How to make non-newtonian fluid:
-Materials-
-Procedure-
1. Pour corn starch into the container.
2. Slowly pour water to the container.
Don't pour a lot at once and mix it with corn starch while pouring.
The ratio between corn starch and water should be about 5:1.
3. Check if the liquid mixture can be shaped as a ball (solid)
by squeezing & rolling the mixture.
if it worked, you just made a
4. Non-newtonian Fluid !
Properties of non-newtonian fluid:
Here's a video about the properties of non-newtonian fluid.
(we spelled the title of the video wrong...)
When stress is applied to the (liquid form) non-newtonian fluid, it exhibits properties of a solid.
By watching this video, you will easily observe the change.
Non-newtonian fluid Labs:
We had 2 different labs with non-newtonian fluid.
-#1. Speaker Lab-
Non-newtonian fluid can form a lot of different shapes.
In this lab, we used a speaker as the force that will change the fluid.
Here's the materials and the video from the lab.
The video shows how the shape of the fluid changes when the volume of the speaker increases.
* Materials
*Note
Everything (frequency, shape of the wave...etc) was the same.
We increased the volume (level 1 ~9) while we filmed the video.
We stretched the plastic bag to see the
change of the shape
in a better way.
* Video
-#2. Marble Lab-
Mr.Novak wanted us to have a lab that can be quantified.
We decided to time how long it takes for a dropped marble to touch the bottom part of the beaker when it is dropped to a non-newtonian fluid.
* Materials
* Procedure
1. Mix and pour the 3 variables :A,B,and C into the 100ml beaker.
A=100ml of water
B=100ml of non-newtonian fluid with 80ml of cornstarch
C=100ml of non-newtoian fluid with 20ml of cornstarch
*we ended up only comparing A & B because we didn't had enough time.
2. Drop the marbles into the beakers at the same time.
3. Observe the bottom part of the beaker to
see when the marble touches the ground.
4. Put down the time it took for the marble to get down in the data table.
* Video
ps. The marble that was dropped into the water beaker (A) continued to spin and hit the beaker while it was coming down. This made the marble A to come down a little slower. However, A was still faster than B!

Water vs. non-newtonian fluid:
Comparing non-newtonian fluid with other liquids (or solid) was one of the required thing that we had to do for this blog project.
We decided to compare water and non-newtoian fluid.
This video shows how water and non-newtonian acts
when they're poured on the speaker.
* Materials
* Note
We had the same frequency, volume, shape of the wave...etc.
for both water and non-newtonian fluid.
We tested 2 variables: when the power range button is on 2 &
when the power range button is on 200.
(Frequency on 0.2, Volume the highest, Smooth wave)
* Video
Non-newtonian fluid only formed small waves while water was splashing all over the place... This difference shows how non-newtonian fluid starts to act like a solid when there is a force.
