MAGICAL UNDERWATER FIREWORKS
I. MATERIALS
 Two Transparent Glasses
 Cooking Oil
 Water
 Fork
 Tablespoon
 Food Colouring (Blue, Yellow, Red, Green)
 Medicine Dropper
II. PROCEDURE
1. Fill one glass almost to the top with room-temperature water.
2. Get the other glass and pour 2 tablespoons of cooking oil into it. Then use the medicine
dropper to carefully drop the different food colouring one by one.
3. Briefly stir the oil and food colouring using a fork to divide the food colouring drops into
smaller drops but do not thoroughly mix the liquid.
4. Pour the oil and food colouring mixture into the glass filled with water to see how the food
colouring sink slowly and expands in the water as it falls resembling the motion and impression
of fireworks.
III. RATIONALE
It is known that water and oil don't mix together no matter how much they are combined, it
is due to the differences in their polarity states. We have different liquid substances, and not
everything can be turned into a homogenous mixture. It depends on their miscibility and
molecular structure to determine whether two different substances are mixed. In this experiment
called “Underwater Fireworks”, Group 3 will exploit the different properties of liquids to create
an underwater fireworks resemblance that shows the diverse colour explosions through a mixture
of non-polar molecules and polar molecules. The experiment will show how polar molecules like
water and non-polar molecules like oil tend to repel each other; they will always remain
separated even if they are shaken vigorously in an attempt to mix; otherwise, they would create a
separate layer, and oil will always be on top because it is denser than water. The “firework” will
appear as the food colours sink to the bottom of the oil and mix with the water. The colour
diffuses outward as the food-coloured droplets gradually fall to the bottom. That means the foodcolouring molecules move from a high to a lower concentration of food-colouring inside the
water. Therefore, the colour of the water doesn’t change immediately but rather through a slow
mixing of both, with some parts of the water still being clear and others becoming coloured.
