Black powder explodes. Flash powder burns extremely fast (that's why it "flashes") and can be dangerous if you don't handle it right.
There is a slight difference between aluminum foil and an aluminum rod or powder. This difference is simply the shape it takes.
Instead of aluminum powder you could use German dark or Indian blackhead.
It varies depending on the particle size of the powder.
It will depend on the oxidizer you are using. Nitrate-aluminum flash powders are pretty stable, but a ammonium perchlorate-aluminum flash powder is extremely shock sensitive. One scrap on the ground and it could ignite. By the way, flash powders (with the exception of ammonium nitrate and aluminum which is explosive) do not detonate; they just burn very fast.
It makes white colored stars. Its' also an ingredient in flash powder.
You cannot buy flash powder online or at any other store - that would be like buying C4 over the Internet. You would need to make it yourself from an oxidizer and aluminum or magnesium powder.

you can't buy flash powder. it is used to make firecrackers and explosives, so it is not commercially available. You can make it from an oxidiser and a metallic fuel such as KClO4 and Aluminium.

how do you separate aluminum powder and salt
Flash powder was invented by a man named Joshua Lionel Cowen. He registered for a patent in 1899 for the flash powder to be used in photography.

Early flash powder was made of thermite. And yes, it was extremley messy and if the pan holding the flash powder wasn't held carefully could easily cover everything

No flash powder is stronger and also more unsafe! I suggest reading up on the matter if you would like to know more.
