Need to create a long drinking straw for a disabled friend, 3 feet or
so. He's currently using a tube from a piece of medical equipment, but
it's not designed for drinking thru, and has a strong plastic taste -
probably all sorts of nasty chemicals leeching into the water.

Its only for cold water, but needs to be flexible. A decent length
that we can snip 3ft pieces off would be ideal.

Anyone know of any sources? TIA.
