Ocean in a Bottle Project


Here’s a science project that doubles as a fun craft. Create your very own ocean waves in a plastic soda bottle. Display for all your friends to see!

What you’ll need:

  • Empty two liter plastic bottle with lid
  • Clear vegetable oil or mineral oil
  • Water
  • funnel
  • Blue food coloring
  • Small star fish, shells and other sea creatures
  • One tsp glitter
  • White craft glue
  • Hot glue

How to make it:

  1. Wash and dry two-liter bottle and remove all labels
  2. Fill bottle halfway with tap water
  3. Add a few drops of blue food coloring and swirl around to mix
  4. Add glitter
  5. Add sea creatures
  6. Fill bottle the rest of the way with vegetable oil using a funnel
  7. Be sure that rim and cap are dry, then apply white craft glue around the rim. Seal cap.
  8. Use a layer of hot glue around the outer edge of the cap for added protection from leakage
  9. Turn bottle on its side and gently rock the bottle to create a “wave” inside your ocean habitat!


  • Use lightweight starfish, shells and other sea creature toys that can float. Test them first in a bowl or glass of water. Find these at your local craft supply store or discount department store.
  • Make the ocean any color you choose! Blue is standard of course, but if your child’s room is decorated with red and yellow, go with red food coloring. There’s no rule that says your ocean must be blue.
  • Small children will be mesmerized by this creation. They can help make this every step. Let them insert the sea creatures, hold the funnel and help add the tap water. In the steps that may be more difficult for little fingers, have them hold the bottle steady for you while you add the glitter.


Lucky Ducks

Lucky Ducks is a game for little kids. Easy and inexpensive to set up and always a favorite at festivals.


You need:

  • Rubber duckies, several- all of the same style
  • A clear container or small baby pool
  • Water, with some blue food dye adds a nice touch
  • Permanent marker
  • Prizes, small toys, stickers, candy, etc.

Set up: Determine how many prize categories you’ll have and divide them up. Three is what I use. Mark the bottoms of the ducks with a 1, 2 or 3. Make a cute sign with the price, if you are charging to play. Fill the container or pool half-way up with water and add the ducks.

To play: Kids pay. They select a duck, pull it out and check to see which prize they will get. Easy!
