Ten years ago, British domestic security claimed to have caught a terrorist cell that had planned to blow up airplanes with a gel they'd carry on in a Gatorade bottle and detonate with an Ipod.
Later that day, British aviation authorities banned all carry-on luggage and, shortly after, aviation authorities around the world announced that henceforth, passengers would only be allowed to carry a maximum of one liter of liquids, in bottles of no more than 100ml.
Ten years later, we still don't know if it's possible to mix a piranha bath in airplane sink without gassing yourself to death, let alone use it to make a liquid explosive in flight.
But we've sure given up a lot of water-bottles.
