Fireworks in a Jar

Materials:

• Mason jar
• Small bowl
• 3-4 tablespoons of oil
• Liquid food coloring
• Fork

Instructions:

1. Add oil to a small bowl. Add several drops of food coloring.
2. Use a fork to gently mix the oil and food coloring.
3. Fill your mason jar about 3/4 of the way with warm water.
4. Slowly pour the oil and food coloring mixture into the mason jar.

The science behind it:

OIl is less dense than water so the oil will float at the top. Food coloring dissolves in water but not in oil. The colored droplets of food coloring will begin to sink because they are heavier than the oil.  Once they sink into the water, they will begin dissolving into the water making a tiny explosion like fireworks.
