GRAND RAPIDS, Mich. — The school year needs to start off with a bang! So we are going to set off some fireworks while learning more about density! Here is what you need in order to get started:
- water
- oil
- food coloring
- 2 clear glasses
- fork
Step 1: Fill one glass almost to the top with room temperature water
Step 2: Pour 2 tablespoons of oil into the other glass
Step 3: Add a few drops of food coloring into the glass with oil and mix those together with your fork. Stop once you break up the food coloring into smaller drops
Step 4: Pour the oil and food coloring mixture into the other glass with water
Step 5: Sit back and watch the mini firework show!
We just created a mini fireworks show! The food coloring dissolves in water but the oil does not. When you pour that mixture into the water the oil floats because its less dense and the food coloring begins to dissolve it sinks through the oil and into the water! There you have it! A cool way to learn more about density differences.
