First you will want to cut out two construction paper strips. I cut mine 1 inch wide by 4 or 5 inches long. The kids could not decide on a single color so we did pink and purple.
Wrap your strips on each side of the craft stick making sure to keep them near the edge with a bit of craft stick still showing.
Wrap a rubber band around the length of the craft stick.
Place the second craft stick under the one with the construction paper strips and using another rubber band, wrap the ends together.
Now your homemade harmonica is ready for playing. Make sure your kids blow on the wooden middle part and not the part covered in paper. Playing this homemade harmonica will require some practice. At first my girls were biting down on the stick which will not allow the breath to travel. But with some practice, we were making music!
