Before they take your liquids, ask them if the 3.4 ounces is by mass or volume. Not a single one has known.

I froze my toothpaste one time and they still took it. I argued that ice is a solid therefore you can't take it and redefine the laws of physics. They said "well when it melts it is a liquid". I replied "if you put enough heat to anything it melts."...they took my toothpaste.

I also don't understand how if humans are 80% water and we're still allowed through. If the average person is 190, 80% of that is 152 lbs of water! Or, 2432 ounces!
