Various salts are added to the mix: . Copper salts - blue . Strontium salts - red . Sodium salts - yellow . Barium salts - green . Calcium salts - orange . Cobalt salts - blue . Cryolite - yellow . Lithium salts - bright red
Chemical change. A good hint for this one is that there is fire involved, which usually means that the chemical itself is being changed. The constituent materials oxidize (burning quickly - explosion - is very rapid oxidization) and form new compounds i.e. the chemicals change.

Any explosion will generally happen symmetrically. When it's on the ground, the ground stops the "bottom" part and you only see the top part. An explosion with an extreme amount of heat, such as a nuclear explosion in the atmosphere will also be influenced by the "heat rises" factor.
Nearly every metal can be used in fireworks. But the most common of the metals include Copper (green), Magnesium (bright white), Lithium or Calcium (Red)... This list goes on and on depending on which manufacturer.
