  1. SMOKE BOMB

  2. Materials • Potassium nitrate • Sugar (sucrose or table sugar) • Chemicals Used to Color Flames

  3. Red - strontium salts • Orange - calcium chloride Yellow - sodium nitrate • Green - barium salts, such as barium nitrate

  4. Apparatus • Hotplate • Satay Stick • Aluminum foil • Lighter • Mould • Wick • Lighter

  5. Procedures • Add sugar to potassium nitrate in the ratio of 2:3 on a piece of aluminum foil. • Add chemical that colour the flame, sparingly. • Heat the mixture on a hotplate on low heat. • Stir the mixture well using a satay stick.

  6. When the mixture turned brown, take it off the heat and wrap the mixture with that aluminum foil. • When it has hardened – takes about 10minutes – light it up and coloured flames will be produced.

  7. Chemistry Behind • Sugar – fuel • Potassium nitrate- oxidizer • Salt- organic dye • 48NaNO3 + 5C12H22O11- 60CO2 + 55H2O + 24N2 + 24Na2O
