Ocean in a bottle

Wednesday, October 6, 2010


The kids each made an ocean in a bottle today (thanks to Holly) at our homeschool group get together. 
They are always a big hit. 
Science is so much fun!

What you 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 plastic toy sea creatures
One tsp glitter
White craft glue
Hot glue
Craft/candle sand (you can use sand from the kids sandbox or the beach, but it is probably mixed with dirt and will just make the water murky)
What you do
  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!
