Summary:
Effects on Cornstarch with high Acceleration Vibrations
-OVERVIEW-




About:
      This is probablly one of the oddest experiments I have ever done. The idea came up when someone sent me this interesting internet
video of a similar experiment. I thought to myself, "This is pretty neat!" I looked into it more and quickly realized I could
do something like this.







Rundown:
      Ok, whats going on here is simple. Under normal conditions cornstarch behaves as a liquid just as one would expect. Under high
accelerations, however, cornstarch solution behaves as an amorphis solid. To demonstrate this, I built several machines that do
nothing more than violently vibrate.







First Attempt:
Here is the first and most successfull vibration machine. It has a washing machine motor attached to a board which was susspend
from a frame by strings and rubber stipping. The motor has a fly wheel with a bolt fimly strung to one side to set if off ballance.
This yields fast, strong, yet subtle vibrations.

            


***WARNING!!!
The bolt attached to the fly wheel undergoes intense centripital forces! It can fly off and shatter a near by window!
I'm not just making this up, I KNOW!!


Second Attempt:
Here is the second machine. Since the results were turning out so good for the first one I figured things could get even cooler if
I ramped up the vibration accellerations even more. I was wrong, this machine just shook itself apart.

      


Results:
In this series you can see that under normal situations, the goop is just a thick liquid. Once the vibrations start, it starts
behaving like a living thing! It even appears to respond to stimuli. It starts with finger like purtrusions. As you increase the
vibrations it builds up and trys to climb out of the container!

I was also able to have it demonstrate memory like properties where as you could use a straw to blow a little hole in the surface,
stop blowing, and like magic, the whole remains! Adjust the vibration accelerations and you can cause that hole to expand, contract,
or even invert and grow up into what looks like an erie beckoning finger.
