You can make one really easily. Get a nice sized pot, and set it up over a few candles. Melt your chocolate of choice in the pot. Dip and enjoy. Just don't use too strong a flame and if possible stir the chocolate every once in a while to prevent burning. Use dark chocolate, it melts a lot better than milk.

The best tings to dip are
Marshmallows
Graham Crackers
Cakes (Cut the cake into small cubes and dip those)
Cookies
Most Fruit (pretty much everything that's not a tomato)
Pretzels (salted.)
