My friend Moriel has a new website called SmartAxe, an extension of her Smarter Than That site. She's trying (and succeeding) in making science education fun and perhaps a wee bit silly.
For Valentine's Day she took on an interesting topic... sex in space. I've had my own thoughts on writing about this, using various concepts -- like "How do you have a candlelit romantic dinner in microgravity?" and "What about Newton's Third Law?" -- to tackle some fun science concepts. Moriel does the same thing at her site, and it makes for some good reading... so do it with the one you love. It's worth it just to see the picture she posts at the bottom of the page.
