How Does It Work?
Water is denser than oil and the two liquids never mix. So when the water moves, it pushes the oil around, making shapes like waves. Take a look at what happens when the 2 are combined!

What You Will Need:
Clear bottle/jar with lid
Blue food coloring
Glitter (optional)
Cooking or baby oil
Plastic floating toys





1. Fill the bottle/jar halfway with water






2. Add drops of food coloring until you like the color you see

3. Shake in a little glitter






4. Pour in oil until the jar is three-quarters full







5. Place a floating toy on top of the oil, then screw on the lid tightly

6. Shake the jar gently to set your ocean in motion
