How To Make an Ocean in a Bottle

Are you looking for a new craft project to distract the kids on a rainy day? Or do you have a science project about waves that needs a visual representation? If so you may consider making an ocean in a bottle. This fun project can take less than an hour while providing hours of fun.

  1. Gather the materials. To create your ocean you will need one clear plastic soda bottle, a funnel, water, blue food coloring and vegetable oil. You can use any kind of cooking oil you prefer. Light vegetable oil will be the closest to clear for a more natural looking sky against your blue ocean waves. Darker canola or olive oil may not create the exact look your want for your new ocean.
  2. Prepare the materials. Empty the soda bottle and remove the label. Wash the bottle so that it is clean and there is no sticky soda residue let inside.
  3. Pour water into the bottle. Fill the bottle with water until it is one third full. Then add a few drops of the food coloring until the water is ocean blue.
  4. Fill the rest of the bottle with oil. Pour the vegetable oil through the funnel into the soda bottle. Make sure the bottle is full.
  5. Close and secure the lid. The bottle needs to be secure so that it doesn't leak or make a mess. Tighten the lid as far as it will go before moving on to the next step.
  6. Hold the bottle and create the waves. Hold the bottle on its side with one end in each hand. Raise and lower the bottle like a see saw. After a few turns from side to side you should begin to notice swirling waves as the oil and water pass over and under each other.
  7. Enjoy your new ocean in a bottle. The bottled ocean is not just a science experiment. It can be a soothing decoration for your home or office.

These simple materials are all you need to make an ocean in a bottle. Since the oil and water won't mix, your ocean won't fade or fizzle. As long as you're willing to make the movements and swish the contents of the bottle, you should be making waves for as long as you desire.
