I've packed some food with in a freeze bag alongside some frozen water bottles in it to keep it cool. But appearently water is not allowed within a size limitation, and that somehow includes ice. I've had to argue for 10 minutes about what is solid/fluid and they eventually let me keep it.

    The sad part is that you’re correct. Ice is specifically allowed under TSA guidelines. I guess because if it’s frozen, it’s “proof” that it’s just water and not anything more sinister. Because flammable clear fluids like alcohol or butane don’t freeze as easily.

  • You can freeze butane solid with liquid nitrogen. Also, considering how long liquid nitrogen lasted in my cheap vacuum insulated coffee mug, I'm willing to bet a brick of butane would also last quite a while. Now you have me debating if trying to get a brick of butane through airport security just to see if I can is worth the risk of being put on the do not fly list.
