Ya, its interesting stuff. We just reused it for a long ski weekend. It was still stiff after 4 days in an extreme cooler.

Not too get too weird, but I'm going to pull together an experiment to figure out the R factor of a large Polar Bear cooler and the specific heat of the techni ice. Given that, the temperature of the food (assuming same characteristics of water) and the ambient temperature I can fit a curve across the data and determine when the temperature of the mass exceeds 32F... This is too hard.

Or, I could just fill the cooler up with -10 degree Farenheit techni ice and 15 pounds of vacuum sealed ice and see how long it takes to melt!

I'm ordering more techni ice so that I can pack the large polar bear so that the contents don't shift. More chill is good too.

Cheers, RickG

I sort of got carried away when I ordered and ended up with 8 sheets.

I have 6 in the freeze right now and based on the shifting factor RickG mentioned, I may freeze the other two this evening.

Can you bring Techni-Ice in a carry on cooler? It's not clear to me from their website or from the TSA site.

This is a great question. I can't get a straight question on frozen solid gels? There seems to be some success using techni-ice to transport frozen breast milk and insulin. But I can't find a thing regarding carry-on for food. If you find anything please post.

If I was doing carry on I would pack all of the frozen items with no refrigerant tightly, with balled up newspaper taking up any extra space. If possible, I would put the whole cooler in the freezer packed and get it all as cold as possible. My deep freeze will go down to -10 degrees Farenheit.

theshopper3's friend Woody was able to get a carry-on cooler with just frozen meat to STJ still frozen even after an overnight hotel stay in Detroit and a long travel day to FLL, STT and STJ.

hmmm... checking the TSA site again, it says this:
Gels or frozen liquids needed to cool disability or medically related items used by persons with disabilities or medical conditions.
which would lead one to think that gels or frozen liquids for other purposes are not allowed, although it doesn't explicitly say that.

I'd be interested in hearing from anyone who knows the answer to this. Thanks!

Waterguy - Yeah, I am glad I didn't wait until Thursday morning, that would have been frustrating.

SJ - you can cut the sheets down to size. Whole (the way I have them) are about 11 x 14. I will weigh one tonight and get back to you.

For the other geeks that are interested in knowing - A full size frozen sheet of t-ice weighs 29.3 ounces.

I am starting to feel like Alton Brown.
