Happy Columbus Day

Columbus Day is celebrated today, to commemorate Christopher Columbus historic sailing of the ocean blue to America in 1492.  Help your children create their own ocean with this cool science project that doubles as a fun craft. 

Empty plastic water bottle with lid
Clear baby oil or mineral oil
Blue food coloring
Small plastic fish, shells and other sea creatures
White or silver glitter
White craft glue
Hot glue gun
Optional: sand

Instructions: Remove the labels from the water bottle.  Use a funnel to pour a cup full of baby oil (or 1/2 way full) into a clear plastic water bottle. Then fill the bottle the rest of the way with water. We give the liquid a chance to settle, then add a few drops of blue food coloring. The kids will have fun watching the blue as it drops through the oil and "explodes" into the water. Last, add the plastic sea items. Apply white craft glue around the rim and screw on the cap.  Use a layer of hot glue around the outer edge of the cap for added protection from leakage. Turn bottle on its side and gently rock the bottle to create a “wave” inside your ocean habitat!

Tip: 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.

Note: I have made these for many years in my classroom. Sadly, I do not remember where I got the idea from.
