SMOKE BOMB
Materials
•Potassium nitrate•Sugar (sucrose or table
sugar)•Chemicals Used to Color
Flames
•Red - strontium salts•Orange - calcium chloride
Yellow - sodium nitrate•Green - barium salts, such
as barium nitrate
Apparatus•Hotplate•Satay Stick•Aluminum foil•Lighter•Mould•Wick•Lighter
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.
• 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.
Chemistry Behind
• Sugar – fuel• Potassium nitrate- oxidizer • Salt- organic dye
• 48NaNO3 + 5C12H22O11 - 60CO2 + 55H2O + 24N2 + 24Na2O
