Clementine Candle.

This idea is sooo cute and really works! I did it with my little cousins the other day and they were awe-struck. This is where I got the idea... the only difference is I put a heart on top instead of just a boring "X"  (http://www.apartmenttherapy.com/ny/how-to/how-to-make-a-clementine-candle-001453 )

P.S. - It works best the next day when the "wick" has dried out a little bit.
