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.
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.
In flight, yeah totally impractical and not worth even trying.
Theoretically, if I were to attempt it, I’d get my liquids through the checkpoint, mix them together and then wait the few hours for the precipitate to fall out. Then go to the bathroom pour that through a handful of paper towels, or even some coffee filters I brought in my carry on. Then, put that into some type of confinement like a metal water bottle. Lined with paper towels to pull the last bit of moisture out of the crystals. A couple more hours later and there’s a pretty sensitive device that could be set off dropping, throwing, hitting, or whatever.
That’s a way. There’s many, many ways that someone could go about it. Also agree with the sentiment that the TSA is complete theater and doesn’t actually do much to keep anyone safe. But they’re working government jobs, getting paid ok-not great, with decent benefits and can get a retirement out of it.
The shoe bomber had what was probably good quality stuff, but he was missed his flight due to looking suspicious and being pulled for questioning, he stayed the night at the airport all the while walking around with these shoes that were hollowed out on the bottom. Probably nervous as hell and sweating all this time, plus walking through puddles and such. He managed to dampen the crystals so the next day when he got on his flight they were too desensitized to detonate.

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

I believe you’re mixing up acetone with acetic acid

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
