Different chemicals give different colours:<br />Red Strontium Chloride or Strontium Nitrate<br />Orange Calcium Chloride<br />Yellow Sodium Chloride (table salt) or Borax<br />Green Copper Sulfate or Boric Acid<br />Blue Copper Chloride<br />Purple Potassium Chloride<br />White Magnesium Sulfate (Epsom salts)<br />Girls want to make fireworks next, think we'll start with sparklers...Helen Allennoreply@blogger.com
