Not a chemist…but if someone can carry on 3 bottles at 3.4 ounces each, now they have 10 ounces.

Two people do it and it’s 20 ounces. All within the “TSA Standard.”

This is where the liquid limit never made sense to me…if we were serious about keeping these substances off of planes, we would limit the total liquid…right? Or require that any liquids get checked.

I just don’t see how per-bottle liquid limits are anything close to deterrent for motivated attackers…but they sure are deterrent for me when I forget that I put a hotel water bottle in my bag.
