  1. Cool quiz. I did ok. I got 13 out of 20. Without Gil's presentation on the different ways water can be filtered, I would have done way worse.

    One question was a little weird and funny though. It asked "What additive can you use to neutralize the flavor of iodine after filtering out viruses?" and tang, the powdery orange drink, was one of the choices. I hesitated because I felt like the quiz was trying to trick me by giving a silly option. But luckily I got it right :) The answer was absorbic acid.
