The video explores the effects of sound waves on non-Newtonian liquids, specifically Oobleck, a mixture of corn flour and water. By using a speaker and a signal generator, the video demonstrates how sound waves can make Oobleck behave like a solid, causing it to 'dance.' The mechanism involves pressure waves jarring the molecules together, temporarily solidifying the liquid. The video also highlights practical applications of sound waves, such as ultrasonic dental cleaning.
