It might not be the safest thing to do with your prized subwoofer. But it’s so much fun! If you’ve never heard of oobleck, you’re in for a treat.
Oobleck is a Non-Newtonian mixture that consists solely of cornstarch and water. When agitated, oobleck acts as a solid. When calm, it acts as a liquid. This is duality in nature is essential for oobleck’s purpose concerning subwoofers.
If placed on top of plastic wrap covering a subwoofer, the oobleck will lie benignly in a puddle while the subwoofer is off. However, once the sub begins emitting sound at low frequencies, such as 20 Hertz, sound waves become visible in the oobleck. As the volume is increased, the vibrations become stronger and the oobleck does much more than mimic the wave patterns of the sound. It begins to jump and dance, wiggle and stretch. It forms strange shapes, thrusting out little tendrils before coming together in eerie humanoid forms. Once you’ve had your fill of dancing oobleck, you turn the subwoofer off, and the oobleck monsters melt back into that same benign puddle of goo.
If you’re afraid of harming your subwoofer, don’t be. Cover the outsides with newspapers, and use multiple layers of plastic wrap to ensure no oobleck leaks through. Once you’re done, your subwoofer should be just fine.
If you want to make your dancing oobleck even more entertaining, add food coloring and watch the way it mixes together. It’s fascinating to watch. It might sound silly, but once you start watching, you start grinning, and you can’t seem to tear your eyes away from the dancing oobleck.
Here’s a little teaser to whet your appetites for oobleck:
