Yes, these look amazing when released, but i know someone who got badly burnt by one when the lighting strip fell on her. Not the scene you really want at your wedding... They are a great novelty but are also a naked flame which is obviously dangerous. Another thing to consider is if they get caught on something? It could cause a fire. And finally they may be biodegradable, but there are toxins in them which harm farm animals if ingested which if they land on farmland, whats tastier than a lantern???
yes theyre a great new novelty, but i think people fail to see the implications of their couple of minutes of joy.
This item can be used for many reasons but if you have lost someone to death, recently, anniversary or whatever, writing a simple message on one of these, lighting it, and watching it softly float and rise to the sky, to the heavens if you wish, is an affordable fantasic idea.
We used them on new years eve and wrote out wishes for the new year on them. They are simple enough to use, the fuel block takes a while to get burning so we used a cooking blow torch because it worked quicker than a lighter and they take a while to heat up inside enough to fly away. But once they get going they look amazing, an it looked like a lot of our neighbours had the same idea and there where loads in the sky which gave a great impact, so if you want to use them you definatly need more than 4, we're going to buy loads more for other occasions :D
