Best Materials for Rigid Drinking Water Bottle

[rastadawg11]

Hello,
Can someone advise me on the best materials (that are also compatible with the Lathe) to use for a rigid drinking water bottle?

Thanks!

Double check me from other sources since there are health issues but I believe HDPE (high density polyethylene) plastic or stainless steel would be appropriate. Stainless would be much more expensive than HDPE.

But guys, Don't you think that a water system is better than affording on bottles....? It is Eco-friendly too...
