Hi B/W -ers!

1/ We must find nonevaporatable tubes (Obvious for me!)
2/ Valves that are not a hole in the lid! (stoneage!)


I found this link to Nalgene:

Wich tube is Soft enought, no evaporationproof?? - also look at the 
valves
- those ventholes has irritades me long by now - just a hole into the 
air- it must be some sort of ball-valve two-ways to hinder 
evapuration even when weather is changing and gives different 
airpressures...

Hunt goes on - I'm now certain that I will find the "things"
Outer Diam 1/8 inner 1/16 (Ah You Americans get used to proper
measuring - inches was was common in sweden and Europe during your 
civil war - are you also building your Spaceships in inches???? Then 
I'm surprised!)/smile/

It seems to me that silicone coated tubes are fit - if not connected 
in three or five - we can do that ourseves - tape or silicone?

Anyone awere of this stuff?

Or I'll must call expensive "long long" phonecalls - Living near by?
