Here’s what you need:
- Glass bottles (mason jars or Snapple bottles)
- Food Coloring
- Stick or something to hit the bottles
Fill the bottles with different levels of water. Add food coloring to them to make the colors of the rainbow. Use any object you want to hit the glass bottles to make noise. We used a butter knife and wooden stick.
After Troy hit the bottles for a while, we talked about the different sounds we heard. He came to the conclusion that the purple water with the lowest amount of water had a high pitch sound and the red water had a lower sound. It was good for him to stop and listen to hear the differences.
Here’s a short video of his music. I love how he blinks every time he hits a bottle!
