If you are a teacher or parent and would like to introduce kids to cymatics and the physics of sound, there are two simple cymatics projects that you can do with kids quickly and easily: “Cymatics In A Glass” and “Build Your Own Tonascope.”
“Cymatics In A Glass” is a very simple way to demonstrate the effects of sound waves for kids. It creates a very cool “vortex” inside a wine glass, in under a minute!
Here’s how to do your first cymatics experiment to demonstrate the physics of sound:
1. Get a wine glass, some food color (darker colors like red or blue work best), and some table salt.
2. Fill the wine glass with water about 2/3 full.
3. Sprinkle some salt into the bottom of the wineglass (about 1/4 tsp).
4. Drop about 5 drops of food coloring right into the center of the water. (Don’t disturb the glass or stir).
5. Holding the stem of the wineglass, with it sitting firmly on the table, wet your finger and run it continuously around the rim of the wineglass (you’ve probably done this before when you were a kid) until the glass is ’singing.’ Keep doing this – going around in a circle, in the SAME direction.
6. Watch the ‘vortex’ form inside the glass! You will also see, if you observe closely, some cymatics patterns radiating inward from the sides of the glass, on the surface of the water.
“Build Your Own Tonascope” is also a very simple cymatics experiment you can do to demonstrate sound waves for kids, letting them use the sound vibrations of their own voices to create amazing cymatics images. Whether you are a student, teacher or parent interested in cymatics, you can learn how to make a tonoscope in under 10 minutes using 3 common hardware-store items now by downloading my step-by-step video instructions…
