So, can you imagine that so many lanterns floating up into the night sky bearing so many wishes to the heavens would be so beautiful? To be honest, I saw them first in Disney's movie "Tangled" - but the tradition is Asian in nature. The northern Thai people (the Lanna) use them year-round. You light them, let the lanterns inflate and then send them up into the sky.
The best part is when you have a group of people who send them up at the same time, even better when sent over a body of water (the reflections, the reflections!)
more simple magic...
