Martini Olive Candle
I picked up this little beauty (the candle, not the glass) at an art supply store. I am looking for an online retailer to feature here

I know that bachelors can not concern themselves too much with candles... the only good scented candle would smell like bacon, and I haven't found that one yet.

This candle however, was intended for guys like us. It's about the size of an olive, and it floats. So get your favorite martini glass, put a little water in it (nothing flammable... c'mon now) and pop in the candle. After a second it will remain right side up and stop moving. Then light it. Instant ambiance... you get chick points for being "romantic" and you're still pretty hip while doing so. This thing was like $.49 too, so I bought a few.

You can buy boxes of these things pretty cheap at DetailsArt.com.
