Although hydrogen is an explosively flammable gas, indications are that the fact that the baloon was filled with hydrogen was not really much of a factor in the Hindenburg crash. Hydrogen burns very rapidly, and because of its density, flames would travel upwards, and be very short-lived. Most of the deaths from fire have been subsequently attributed to the aluminum paint used on the balloon.
Hydrogen
The Hindenburg disaster ended rigid airship aviation for commercial purposes, and since then no zeppelin has ever been used to transport passengers or cargo.
Hydrogen!
The gas was Hydrogen.
YES
It will turn aluminum black

because the vinegar can react with the metal
Jasco - it's a chemical used to remove paint. You could use a heat gun, but the aluminum will take a lot of heat before the paint starts to peel off.
we can use any paint directly.... but for gr8 result we can do a paint of smart materials....or we can do aluminum coating on it...
Mostly acidic foods such as egg yokes, artichokes, and some fruits could react with the magnesium/aluminum alloy used in pans.
The Hindenburg was originally intended to be filled with helium, but a United States military embargo on helium forced the Germans to modify the design of the ship to use highly flammable hydrogen as the lift gas. (At the time the USA was the only country that could produce helium in the amounts required.) The Germans had considerable experience with using hydrogen and implemented necessary safety measures to preempt an accident. Prior to the Hindenburg disaster, their safety record was impressive.
Aluminum powder has many uses. It is highly flammable and used in many explosives. It is also used to make silver metallic pigments or aluminum bronze for paint. It can be used to lift fingerprints at a crime scene. It is also used in many rocket or missile fuels.
You should aviod the use of aluminum pots, pans, and prepware that comes into direct contact with food you are canning. The salts and acids of foods can react with it.
Because it's a lighter-than-air gas. Hydrogen could also be used, but hydrogen is extremely flammable, as the makers of the Hindenburg found out, whereas Helium does not react with oxygen and therefore will not burn.
