Fun With Non-Newtonian Oobleck!

Non-Newtonian fluids are strange. They can act like a liquid, or, depending on the force applied, act like a solid. A suspension of corn starch and water is an example of a non-Newtonian fluid that you can experiment with as you’ll see in this week’s video. I used an amplified speaker covered in some plastic wrap to hold the mixture know as “Oobleck” which derives it’s name from the children’s story “Bartholomew and the Oobleck” by Dr. Seuss. The sine wave is generated by my laptop running a free program called True RTA. It’s a real time frequency analyzer available for download. When the sine wave is played through the speaker, strange things happen to the Oobleck and it rises up to dance around!

Have fun with this one and… keep on hackin!

  1. You said something I didn’t follow… You said the 9 transistor radio used JFETs, “which my cat would really like.” Huh? Sounds like they’re made with catnip. :-) What did you mean?
