eBay with Just Deals has the 10-pack Sky Fire Floating Chinese Sky Lanterns for $20 with free shipping. Handmade self-propelled lanterns features a built-in fuel patch, up to 15 minutes ascend time, completely biodegradable, and each measures 15" x 22.8" x 40.6".
Does sending flame lit balloons into the sky when the hills are tinder dry sound like a bad idea to anyone else?
In the ensuing inferno, saying that they're biodegradable is redundant.
