Demonstration of how tuning forks carry energy when vibrating and what happens when vibrating tuning forks are dipped in water.
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.
Shows how sound vibrations can make objects move, demonstrated by grains of salt moving on plastic wrap when exposed to someone’s voice.
Explains that sound is caused by vibrations.
Explains that sound is caused by vibrations.
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 potbeing hit next to it.
Animated video about vibration and sound waves, and how vibration is used when instruments make sounds.
Shows how pushing or pulling on objects can create vibrations that move the air, forming sound waves.
Shows how sound vibrations can make objects move, demonstrated by rice bouncing on a plastic-covered bowl when exposed to sound from a speaker.
Shows examples of similarities and differences between plant parents and offspring.
