He choose not to debate the science of ice to the TSA agent. BUT saying that, I am gonna test this one as well next time I fly
Using this logic, we now have a new category of newly-prohibited items: "
future liquids" or perhaps even "
potential liquids."
I did some checking and hydrogen peroxide, apparently one of the ingredients of the liquid explosives, freezes at about 12 degrees F and freezes into a crystalline solid. So, it wouldn't even look like frozen water and would be a heck of a lot colder. So, a TSO should logically conclude that the solid substance in the plastic bottle was not peroxide.
Concerning dry ice, I believe it is an FAA-banned item? (Not sure, but I think I'm right.)
