Graduated Sound Bottles

Materials:

1. Bottles (3) 
2. Beads or dry beans 
3. Adhesive 

How to Make:

First, clean out bottles and remove any labeling. Next, fill your bottles with different amounts of beads or beans. I like using translucent plastic bottles so that there isn't much color because it makes the work more auditory instead of visual.  Seal the caps with adhesive and close tightly.
