alt Hacker NewsI'm fine with some liquid potentially being explosives, but the fact that security just throws them all in the same bin when they confiscate them makes me think that not even they believe it makes any sense.
Also, why 100ml? Do you need 150ml to make the explosive? Couldn't there be 2 terrorists with 100ml + 50ml? All these questions, so little answers...
Liquids are not explosive, they are assumed to be used to make explosives once onboard.
Regarding quantity, hard to find information, I guess they don't want to have a terrorist handbook to making explosives online, but I would assume that 100ml would mean multiple times this amount would not be enough to make an explosive large enough bring down an airplane.
In general, considering the overall cost of the measures, I would think that there is a valid reason and that "it does not make sense at first glance so it's just a security theater" does not hold.
