I think this is one of my greatest ideas. Its afordable, easy to make, environmentaly great, fun, and fashonable. This is my instructable for the converse contest so please vote for me.
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.

Step 1: Stuff you will need

Picture of Stuff you will need
Here is the list of all the ecological materials you will need to achieve the task:
2.Silacone seel (this stuff is made out of sand and entirely non-toxic)
3.Bulliten board cork
5.Sand paper
7.Razor knife

Silicone sealant isn't "natural" and sure as hell is not made of sand.
RastaMonkey (author)  CaseyCase5 years ago
yah it is, do you know what silacone is. its a natural mineral and it makes up a lot of sand
No that's silica.
Silica is reduced to silicon in an un-eco-friendly way, then converted to silicon tetrachloride, and so on into silicone polymers (un-eco-friendly).
(You should check the spelling in this)

lemonie nails another one :-) If you wanted a "natural" seal, and cork wasn't cutting it, you'd bee looking for Vulcanized natural rubber. Synthetic rubbers are SO superior to natural rubbers, in EVERY regard(other than their initial petroleum parent) that there's really no reason to even try though, unless you happen to have a Para rubber tree or fields of poinsettias from which to harvest natural latex, and nothing better to do with them.
There's a few million tonnes of natural latex go into tyres every year, synthetic rubbers are not so superior in every way.

Hey, I just spotted this. I would like to add that the initial cork harvest from the tree is pretty poor quality, and usually gets used to make compound agglomerated cork, which involves adding binders such as glue and plastic among other things. And bottle corks, depending on their required properties, are soaked in various chemical baths, including chlorinated lime and peroxide. I guess the more natural you want to be, the more performance you need to sacrifice.

This is a pretty cool Instructable!  I've heard that lots of bamboo, especially the imported kind, has pesticides in it, so lining it is a good idea.

Where did you get the bamboo that big?
Good idea but poor construction. Photos could be improved and text needs some improvement. Looks cool overall, I'm gonna try as soon as a I get some time! Thanks

What diameter Bamboo section would you need to hold the same amount of water as say a 20oz bottle of water? I know you are trying to be eco friendly and all, but wouldn't re-using a plastic bottle and eventually recycling it after many uses be somewhat better since the bamboo will degrade and possibly put toxins in your water once the inside starts to rot? And yes, i know that if you freeze the bottle or expose it to extreme temps would also put toxins in the water...but lets say I am smarter than the average bear and don't do that. Or if I discover that it did happen I recycle the bottle.
Not really. There is , as far as I'm aware, virtually zero toxins in bamboo. Also, it's gonna take a LONG time to decay. Bamboo is pretty stern stuff. As to recycling plastic bottles.... that's great(though opinions vary as to exactly what chemicles are leeched from which types of plastics, under different conditions). But you'd be even better off recycling a GLASS bottle :-) Nothing to lech, it's basically made from sand, and if left to "rot", returns to sand(or pretty pretty beach glass at least). Bamboo, at least in the States, is a non-native, invasive species... so harvesting it here, unless on federally protected, or private property, is actually doing the environment a service. It's not as bad as kudzu or Africainized bees, but it can get out of hand in the right conditions(if cypress likes it, so does bamboo). To answer the size question, approximately a 6" long section of 2"ID bamboo tubing should hold over 1/2L... which is also pretty close to 20oz.
It takes a long time to decay, but a remarkably short time to crack and become useless as a water bottle : )

cool ible.. bad science
Yes the science may be bad, but that is correctable. Instead of demonizing the writer should we not strive to become better teachers ourselves.
Silicone sealant is entirely synthetic, and is harmful to ingest before it cures. However once cured is harmless unless you try to eat it or it becomes brittle and begins to mix in with the water, a rubber O ring would be the better choice here.

The following is from Wikipedia:

Silicone's are synthesized from chlorosilanes, tetraethoxysilane, and related compounds. In the case of PDMS, the starting material is dimethyldichlorosilane

more available at, http://en.wikipedia.org/wiki/Silicone just do your research and update your ible, as it is cool, also please, please do a spell check before posting next time.
