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.
