    According to the story I heard as to the origin of the “no liquids over X amount” rule, years ago there was a terrorist that tried to smuggle hydrogen peroxide and acetone - which can be used to rather easily synthesize triacetone triperoxide (TATP, a highly sensitive explosive) - onto a plane in plastic toiletry bottles. They got caught and foiled somehow, and then the TSA started restricting liquids on planes. This was in the immediate aftermath of 9/11, if I recall correctly.

    And I happen to know, from a reliable source, of someone who accidentally made TATP in a rotary evaporator in an academic lab. So it seems plausible.

    Not that the rule is actually effective prevention against similar attacks, nor that the TSA even knows what the reason is behind what they do at this point, haha. I just thought it was an interesting story.

      hydrogen peroxide and acetone

      So there are worse cleaning chemicals to mix than bleach and vinegar

        Requires an acid catalyst for the reaction to actually proceed, but yeah, could definitely ruin your day - although a lungful of chlorine gas is nothing to sneeze at either.

          No, acetone and peroxide, and generally a small amount of HCl as a catalyst. Makes triacetone triperoxide (TATP). It’s a primary explosive, but far too sensitive for real legitimate work. It’s primarily used by terrorist organizations because it’s easy to acquire the material and easy to make. The infamous shoe bomber had TATP in the soles of his shoes, fortunately the TATP wasn’t completely dry and that’s why he had trouble getting it to go off.

            Dry ? How is anyone going to dry this much liquid to make an actually dangerous amount of explosive while on a plane and not getting detected ?

            Sounds highly implausible

      At least they haven’t taken away our shoes. And is there a limit to the number of 3 Oz bottles you can carry?
