I am not sure this is where I should post this but I thought I would try. I was reading in a magazine (in the doctor's office so I could not take it home to look into it more) that when the weather is very hot like now and you wish to mail plants or perishables to include a little bit of dry ice. They said it would keep the plants cool and would evaporate with no wet mess. Is anyone familiar with this? Could it possibly work?
Dry Ice

Back in the bad old days when I had a (shudder) job I used to ship frozen epoxies in dry ice. It will keep things frozen to -40 degrees if packaged in a styrofoam cooler. It should work for plants but it would have to be contained in some type of cooler or it would gasify too quickly.Dry ice is frozen carbon dioxide and when it thaws it becomes a gas so it is not "wet".Also for plants a small quantity would seem advisable as not to freeze the plants.BTW dry ice is NOT a regulated substance for shipping purposes although it creates fog when it thaws and looks a little eerie.

and if someone opening the package touched it, they would get burned.
and wouldn't that to the cost of postage, and also you have to hunt for it.
