I wondered "What are Sky Lanterns" and found the following information
Sky Lanterns are constructed of oiled rice paper in an Asian tradition dating back hundreds of years and have been called the first hot air balloon
. These small lanterns were used as signaling devices during early Chinese battles. Also known as Chinese Lanterns or Flying Lanterns they contain a small candle or other fuel cell which is lighted and allowed to sail away. When each guest at a celebration is given a Sky Lantern to release into the night sky it is an awesome sight.
Sky Lanterns can be found in many designs, colors and sizes suitable for any occasion from a birthday party or wedding, to even a funeral celebration of life. With modern development of LED lighting they can be found suitable for hanging from trees, within buildings or anywhere you might so desire hanging them for your festive occasion. These Lanterns can also be special ordered with what ever type message you might choose to have printed on them, making them very special for celebrations of any type.
I especially like the Lanterns shaped to resemble white doves for release after a wedding by the friends and family to be a very lovely idea. What a beautiful experience of eye candy for the bride and groom as well as their guests to carry the memory for years to come.
The knowledge of these Lanterns all being one and the same item removes any confusion when reading about or observing these Lanterns in use. So they are well worth a look.
