Description
A fun and educational science experiment that creates a stunning visual of ocean waves in a jar.
Ingredients
- Clear jar or glass container with lid
- Water
- Blue food coloring
- Vegetable oil
- Salt
- Small funnel (optional)
- Tray or towel (to catch spills)
Instructions
- Fill the jar about halfway with water.
- Add several drops of blue food coloring to the water and stir gently to mix.
- Stir in a teaspoon of salt to the colored water to help create wave movement.
- Slowly pour vegetable oil on top of the colored water until the jar is nearly full, leaving some space at the top.
- Secure the lid tightly and gently tilt or shake the jar to see the ‘waves’ form and move inside.
- Watch as the oil and water move separately, creating rolling waves inside the jar.
Notes
Use a funnel while pouring the oil to reduce spills. Adjust the amount of blue food coloring to achieve the desired ocean color. Experiment with different types of salt to see how it affects the wave movement.
