how do u get aluminium powder - Instructables

a relatively easy way to make this (if you have the tools) is to blend or grind aluminium foil in an old coffe grinder/blender, then to ball mill the rough powder that comes out sorry, you can only really get into pyro/bomb making if you have a ball mill its cheaper to make one yourself, btw if you can't do it this way the best your gonna do is sandpaper a block of aluminium then ginding it ,
