Materials: 2 cups of cornstarch, 1 cup of water, a subwoofer, a thin metal cookie sheet, a few MP3 recordings, food coloring
Place the cookie sheet onto the speaker of the subwoofer.
Mix the cornstarch and water and pour this mixture onto the cookie sheet.
Download different songs and see what works best for you. It works best to experiment with 40 Hz, 50 Hz, and 63 Hz with the volume turned up.
While the oobleck is dancing, carefully add drops of your favorite food coloring for a colorful surprise!
Try searching for a subwoofer test MP3 for best results.
How does it work? The oobleck is a non newtonian fluid, since it can act like both a solid and a liquid at the same time. When vibrations are applied through music, the cornstarch is able to hold its shape.
