A sky lantern (hot air balloon, made of paper) which is made to resemble a reasonably accurate scale model of the Hindenburg.

Light the burner and allow the envelope to fill. Release the balloon and watch it ascend majestically.

When the burner fuel is consumed, a fuse ignites the envelope and it plummets burning from the sky.

Carefully designed so that the envelope burns out completely before reaching the ground. Total cold fallout, so no risk of fires.

// no risk of fires// [8th], are you feeling quite alright?

Will there be miniature burning people running away from the crash impact site? (waves tempting croissant around pending answer)

^ Oh now that's just mean. They should be falling out of the H, some with little burning parachutes.

[+] Would suggest a match fusee (slow burning match) used as a timer for directional changes, as well as a buoyancy source.

I attended a lantern festival on the shores of a very small park in Asia. The burning lanterns would arc over the riverbank and back into the trees next to us. I was sorely tempted to jump up shouting "Fire! Fire!" but I was surrounded by blissed-out Buddhists.

The beauty of a sky lantern is that it burns out or simply disappears, so [-].

Why is it beautiful if it burns out? In this idea, the lantern also burns out before it hits the ground. Some lanterns have landed and caused serious fires, but in this case provision has been made to prevent that, making it a doubly good idea.

I'll admit to being biased from seeing entire skies, big city alleys and plazas filled with floating lanterns, but I'd want to see details of actual fires in Asia, where lanterns have been set free since willy and nilly first had children. Watching one disappear is a great deal of their beauty.

The fuse should trigger the release valve of a small pressure tank of hydrogen, venting into the envelope.

Great, let's see you engineer that so that the whole package still retails at less than USD$5 a unit.

You are changing the parameters as we go along.
