(sigh) My wife already is upset with all the stuff in the fridge (still have lots of 120/220 and 35mm film in there), and another jar might get her more upset, haha. I'm trying to keep it discreet in the fridge, so might stick with the ziplock plastic bag... :)

Still on the latex tube topic:

In the Philippines (about 30-35 centigrade and 80-100% humidity year round), my old latex tubes have become either a sticky mess (that tears more easily than bubble gum) or dry and crumbly.

A LBS once sold michelin latex tubes, but they got old in storage, and were dry and crumbly (I bought one, inflated it, and it popped/teared almost immediately; got a refund).

Still... there are tubulars sold here, and they do have latex tubes in them, right? Hmmm...

Anyway, since I am saving my latex tubes for race only, I am putting them in a ziplock plastic bag and putting them in the fridge. I hope that works (I buy new latex tubes for major races -- not locally, but from Amazon or ebay, not because I want new tubes, but because the old latex just deteriorates/rots. Am thinking it's because of the climate?)

Have you thought of using a vaccuum sealer? ( you are doing sous vide, and I find this SO much better than the archimedes principle and ziplocs ). 2 birds, 1 stone

I am using a vacuum sealer (I said so in my post). but, I wrap them in a paper bag first to protect from light.

I use my vacuum sealer for all kinds of food items, and, assuming the seal "holds" - then food preserves well. To be fair, I don't intend to eat my latex tubes - but, who knows? New research published here on ST might prove that eating latex tubes will make you more aerodynamic and shave 3 seconds from a 40k TT :-|

we keep everything in A/C including the bikes (since we live at the beach rust is a huge concern also). I haven't noticed any problem wtih tubes on the longest (5 hour) training ride but i also rarely flat. sounds like our weather is the same but we do dip down to the high teens on very rare ocassions in teh winter. our summer is Feb through Nov. :) temps generally in those months at least 30 and normally 32 to 33 and up to 35. dunno what numbers our humidity is but i know it is super high - enough we shower 3 x day.

oh golly, i'm an idiot. i had no idea that there was anything other than a black (normal) tube. (cue Gilda Ratner impression)...nevermind.
