As he also mentioned, it has to be completely solid ice. Partial mixtures of ice and liquid, or a slush, are still prohibited.
( * - something about the freezing point of liquid explosives being prohibitively low, on the grade of requiring liquid nitrogen. I didn't pay too much attention to the science part of it; just sucked up the meat and potatoes and went on my way. )
As for this particular topic, sorry: I can neither confirm nor deny it at the time.
Sorry Dean, but I do pay attention to the Science. I have been informed that the TSA is worried about peroxides. Concentrated H2O2 freezes at about -15 C, which is perfectly attainable in a common freezer (typically goes to -20 C). Sure, the imaginary terrorist would have to carry the bottle in some kind of way not to let it melt partially, but either using dry ice up to the checkpoint (
not hard to get) or simply throwing the melted part away would do the trick.
I have a feeling this rule was created as a post-Britney cover-up...
