I remember making these when I was young. Remembered the difficult part was sealing the tube at the end. I'm glad to see that Nat liked them so much. He was totally engrossed with scooping the green beans with his spoon and hands. Although he only played with them for about 2 months, it's okay. It's a musical toy that was totally recycled and probably just cost 5cents. Once in a while, he still takes them out to be his microphone or just providing music for his live concerts or worship session at home.
