Create an ocean in a bottle by trying a test on oil and water. When you're finished, you can turn this science experiment for kids into a decorative display.

What You'll Need:

  • Funnel
  • Clear soda bottle
  • Water
  • Cooking oil
  • Blue food coloring
  • Glitter

Step 1: Using a funnel, pour 1/2 cup of water and 1/2 cup of oil into a soda bottle.

Step 2: Put the lid on tightly, and shake the bottle vigorously to mix the substances.

Step 3: After shaking, put the bottle down and let it sit for a few minutes. What happens to the oil and water after you mix them?

Step 4: To turn your experiment into an ocean display, remove the top and add enough water to fill the bottle 2/3 full.

Step 5: Add a few drops of food coloring and some glitter, and shake the bottle gently to mix in the color.

Step 6: Fill the rest of the bottle almost to the top with oil.

Step 7: Put the top back on tightly, and gently tilt the bottle back and forth to create an ocean wave effect.
