Shows how when placing sand on a vibrating surface, different sound frequencies cause the sand to arrange into distinct geometric shapes.
Shows how to make sprinkles “dance” using sound waves.
Shows how sound vibrations can make objects move, demonstrated by rice bouncing on a plastic-covered bowl when exposed to the sound of a metal pan being hit next to it.
Shows simple experiments that visualize sound vibrations: using a tuning fork in water to create splashes, placing rice on a vibrating surface to observe movement, and utilizing a balloon to feel sound vibrations.

Shows acoustic levitation, a phenomenon where ultrasonic sound waves generate regions of high and low pressure in the air, allowing small objects to be suspended without physical contact.
