Blimp envelope inferno

First off, I wish to apologize for the dark&crappy image quality, my friend didn't know how to adjust the camera correctly.

What you should see: I took a 20 liter, old and leaky foil balloon (used as a blimp envelope) and filled it with pure hydrogen gas. I then attached a long gunpowder fuse to it, tied the balloon to a string, anchored it, and lit the fuse.

From the start, we can see some sparks falling down from the suspended balloon. Then a small white glimpse occurs (the initial puncture and ignition). Few moments after that the tail section catches fire, and the flames slowly engulf the whole works. After the hydrogen has burned away, the remains of the balloons fall down.

What you should note: This balloon was inflated with pure hydrogen gas. The flame was actually very gentle, and no explosion occurred! This is because the hydrogen inside had no oxygen to burn. combustion occurred only where hydrogen met air (the puncture). It took some time for the fire to enlarge this tear and burn the whole balloon. All and all this fire resembles closely the one seen in the Hindenburg accident: the thing didn't explode, just burn.

Come to think of it, I've seen gasoline burns and gas vapor explosions doing much more damage than hydrogen fires. hydrogen (being lighter than air by far) tends to escape very rapidly. On the contrary, gasoline vapor is heavier than air, condenses on surfaces, soaks into clothing and remains in a room creating an extremely high risk for explosion. for fuel, I would choose hydrogen over gasoline...
