The bottle is made of one section of bamboo with one section cut off for the cap. I used cork to fit the cap inside the bottle. Really thats all you need to know to make a bamboo bottle but I will guide you step by step.
One of the cool things about this instructable is that it requieres 100% natural materials (woohoo) so no cheating and useing artificial stuff.
Last but not least: if you feel that my bottle could be more perfect and awesome than it allready is, please coment and express your feelings.
