We all have seen rainbows. What if you could put up a fire display in the colours of the rainbow? Start by assembling these commonly available materials.

INSTRUCTIONS

1. In 5 fireproof glass dishes, place the materials (lithium, bleaching powder, borax powder, kerosene and potassium chloride) in the order of the colours of the rainbow.
2. Add the rubbing alcohol to the different materials, and light them up.

RESULT

Each flame will burn a different colour based on the material it is burning.
