Hi Folks, This subject is probably best suited somewhere else, but there seem to be plenty of scientific minds on Paddlewise, and as most of you appear to be locked away in the cold and dark, it may be a challenge. Santa Claus, AKA my wife, has given me a stainless-steel vacuum flask. It is a replacement for the previous two, which failed to insulate the contents. The first one, bought at REI, lasted a little over a month, while the second lasted a week. As they are a very simple construction, with only one external seam, I don't understand how the vacuum could leak (is that what vacuum's do?) unseen. This is the only way I can figure that they have failed. Any suggestions?

My wife and I have had the same couple of stainless steel thermo bottles for years now. They have been heavily used too. Thier brands are respectively MEC and EMSA. Thier only fragile point is the kork. >As they are a very simple construction, with only one external seam, I don't Heard of one who tried to weld a handle on the bottle - whizzz..... No more vacuum. :-) Regards -- steen --- *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
