I have a perfectly spherical lead weight that weighs 1 kilogram. I drop it from the surface of the ocean directly into the Mariana Trench. How long does it take to hit the bottom, and how fast is it traveling when it hits? [more inside]
What interesting things can I be doing at the beach and marsh while it's too cold for the usual summer activities? Sciency, educational, artsy craftsy, exercise/activity...
What unique activities could I be doing at the beach and the marsh over time to take better advantage of both while it's too cold for swimming, sunning, and the usual beach activities? Educational things, amateur science experiments/measurements, artsy craftsy things, exercise other than jogging, etc. Let your imagination run wild. [more inside]
I'm not a very good swimmer. I can tread water, float on my back somewhat, and do a mediocre backstroke. But in a few months I'm going to Hawaii, and I'd like to have some fun snorkeling. What swimming skills should I focus on trying to learn? Should I start with learning finless swimming things first, such as the front crawl, or jump right into using fins and snorkel? [more inside]

My sister and I want to take a cheap cruise over the summer. I'm 22, but she's 19. Are there cruise lines that let you drink at 19 in international waters? Also, does anyone have any recommendations for cheap-ish (doesn't have to be dirt cheap, just reasonable) and fun cruises?
Is there a book or museum or resource that specifically lists the stories of people who survived in Lifeboats? [more inside]
If everyone in the world got in the ocean at the same time, how much would sea levels rise? [more inside]
Waterfilter (heh) — so, I have a couple of water-related questions born of a drunken debate among friends. First: what is the difference between a coast, a beach, and a shore? Second: is Puget Sound part of the Pacific Ocean, an entirely separate body, or some freakish combination of the two? Finally: when Seattleites go down to the Sound, are they going to the coast, the beach, the shore, or something else? [more inside]
