The Hindenburg was filled with flammable hydrogen, but recent research suggests that hydrogen wasn't the only dangerous material involved in its tragic demise.
Do you think an aluminum can would behave in the same manner as powdered aluminum? Why or why not?Do you think an aluminum can would behave in the same manner as powdered aluminum?
No. Aluminum and many other substances that are impossible to ignite in solid form may ignite vigorously, even explosively, in the form of a powder suspended in air. Throw a match into a pile of ordinary flour, and the match just goes out. Get a room full of fine flour dust suspended in the air, add a spark and you have a powerful explosion. Same with aluminum.
