As a matter of interest, could you actually carry concentrated H2O2 in a 'typical' airport beverage container - plastic bottle, paper cup etc? I'm a naval historian rather than a scientist and I know the Germans had enormous trouble finding suitable containers when they were using the stuff for submarine propulsion, obviously they did not have modern plastic packaging available.

Also surely the TSA should regularly test the terminal air quality so as to ensure there is no contamination of the 'tests'.
