A friend of mine reccommended these little beauties after she released one on Christmas Day. These are chinese lanterns, and the tradition is to write a wish on the lantern (they come with a marker pen) and then let it drift far far away to the land where wishes come true. If you like the idea of fireworks, but don't have the budget then these are just great. You can imagine how magical a night sky would look, lit with 100 or so of these released by your guests into the air. A nice way of involving everyone in your special day, or perhaps just the bride and groom release one together.
