i think thats what they are called. as some of you may know if youve seen my potato gun, im a bit of a pyro, i would like to make my own fireworks (i know how sorta) but i want the explosion to be colored. were gonna mess with some stuff that changes the color of the flames in chem class but, she wont tell me where to get these salts. do you know anything about them and where i could find them?
