I am gonna make a bamboo cup and i want to know if my bamboo is toxic?

i dont know what type of bamboo it is but just in case how would i make it so its not toxic?

Unless it has been contaminated from external sources, bamboo is not toxic.

Some bamboo is toxic google it
I searched "bamboo toxins" and it appears that only the shoots of some species of bamboo contain toxins.
Is there anything that i need to do to the bamboo before i use it as a water bottle?
Actually, you don't have to do anything to use it but if you want it to last, I recommend you saturate the inside with mineral oil. That will help prevent the grassy taste of bamboo from tainting the water and it will aid in stopping the bamboo from becoming water logged and then cracking when it dries out.

Hi, just curious if this project came to fruition? I just got a huge 6" dia bamboo pole to cut up and use for some landscaping, and i was left with some large scrap pieces that i thought would make a nice cup for holding something like pens, utensils, or maybe even beer.

But as i understand it most bamboo (esp imported) is required to be fumigated with fungicides and other chemicals of dubious safety.

So unless you know exactly where the 'boo was grown, i would be reluctant to put it in contact with food.

cheers,

David

Would inseed oil do?
in my opinion linseed oil is not a wrong choice. during 'drying' it will need oxigen (it's not realy drying, it's a chemical process of oxidation), but after that you wil get a surely nontoxic surface. if parts of the oil which are soaked in deep don't 'dry' the surface will be sort of self-healing against scratching. you should just make sure that the oil is either pure or that everything that is added to it is nontoxic.
I wouldn't recommend it. It can take a very long time to dry and sometimes it never completely dries, it just turns gummy. Boiled linseed oil may have drying additives that are toxic or leave a bad taste. I wouldn't treat the bamboo at all if linseed oil was my only choice.
You can buy a pint of mineral oil at your local pharmacy for a couple of dollars, that's what I would do.

Should i let it dry first so all of that water is out and not sealed in
Yeah, the drier it is the easier the oil will penetrate the bamboo and you will want to saturate it with as much oil as you can.

Thanks for your help i like to know everything about somthing before i try it.
Here's my two cents worth. If your that concerned with toxions and want to seal it, get some bee wax and melt it and use to coat the inside of your bamboo. Don't need to over engeneer on something like this, it's been used for centuries this way.
Gotta love the related panel.  This 'ible:
http://www.instructables.com/id/ECO-FRENDLY-BAMBOO-WATERBOTTLE/
shows how to make a drinking vessel from traditional materials, like bamboo, hemp,  and RTV-silicone.
The process for "making" cork also involves chemical baths for bottle corks, and adding glue and other binders to the poor quality scrap stuff to make compound agglomerated cork.
Yeah... I had overlooked the "cork",

That bulletin board cork is definitely an engineered wood product of some kind.

In this way, bulletin board cork, or wine cork cork, is much like the chicken nugget, a staple food of my people, the Former Americans.

I am guessing your country has chicken nuggets as well.  If you don't, the nuggets a like the "cork", except they are an engineered meat product, made from real chicken pieces, plus binders, plus, um... I don't know what... eleven herbs and spices?  Something like that.
