There's room for both. You can have security checkpoints where they check your bag for liquids, and you should be allowed to fly with them once they confirm its innocuous.

I'm no chemist, but I can't imagine it's hard to test if something is an explosive or just body cream. To pack a punch, I have to imagine explosives need very specific compounds in them.

1) its way harder than you'd expect as many compounds are safe in low concentrations and have other uses. Take TATP- triacetone-triperoxide. yes, the peroxide and acetone(nailpolish remover) in most people's bathrooms should never be mixed.

2) might want to look up how often firearms make it onboard in carry on bagage accidentally. This isn't the typical snarky use of that phrase- it's just so insanely common people don't want to beleive it.

Then we should limit peroxide and acetone, sure.

I think it's perfectly reasonable to forbid >100ml of acetone in flights, and allow people to bring in, say, a bottle of water or a can of orange juice. We can certainly test if something is acetone or orange juice.
