You can have a calm ocean even if you can't go to the beach What you need:

• Clean, clear plastic bottle with cap
  Water
  Baby oil or mineral oil

Here is what you do:

1. Fill the plastic bottle halfway with water.

2. Put three to four drops of the blue food coloring into the water.

3. Put the cap on the bottle tightly.

4. Shake the bottle to mix the color into the water.

5. Take the cap off of the bottle.

6. Pour the oil into the bottle almost to the top but leave some space. (Add the shells or fish if you have them.)

8. Rock the bottle slowly from left to right.
