Simple product to make. Just goes to show that slow people will buy anything. Even if I thought I would need that product here goes:
1. Mouthpiece with strap- $1 USD
2. Burlap sack- $00.25 to $00.50
3. Rocks- Free
4. 5 minutes of my free time- Free
Come on man you are acting like you are some state of the art engineer.
