text: any interesting questions that deal with physical science? something thought-provoking or just fun, but interesting, its for a class project - short research paper. i have tons of interests (so i cant decide) but had to get stuck w the person with no interests at all (so i need something interesting)! thanks, we'll put it to a vote hmmm..like what would happen if we dug a hole through the centre of a planet all the way to the other side and jumped in? or how physical science is used in elaborate "magical illusions"?
