Those who believe can send a jack-o-lantern soaring with these sky lanterns. Made from flame-retardant materials, they'll glow eerily as they float silently, slowly upwards, lasting 12 to 20 minutes in the air before they extinguish themselves. All you do is light the attached fuel cell and hold the lantern until the heat fully inflates it, and then you can release it and it will drift upwards. Available in packs of 5,10 or 25, they are currently on sale. My order for a 10-pack today totaled $33.35 including the shipping charges.
Sky lanterns really make an impact when released in quantity.
Here's a 48-second video showing the effect of wish lanterns set adrift en masse at a celebration of the full moon in the capital of Thailand. It's spectacular.
