One of my many stories right now is about mermaids. I began wondering then about how far down a storm can be felt, which caused me to stumble upon an FAQ about submarines. Now, normally, I don’t like about.com but this page was actually rather useful. Not only did it give me my answer (Hurricanes can distort water about 400 feet below) but it answers about 49 other questions about submarines. It also gave me a few thoughts about space ships. Might be worth a glance at.
