This week in Under the Sea camp we learned all about the ocean and the fascinating creatures that live there. We also did lots of cool experiments that taught us about water. We experimented with water and oil and learned that some liquids are denser than others. When oil and water are mixed together, the oil always rises to the top because it is a less dense liquid. Here’s a cool experiment that also doubles as a fun craft! Create your very own ocean waves in a plastic soda bottle! Head on over to kaboose.com for this experiment and other fun crafts for kids.
What you need
- Empty two liter plastic bottle with lid
- Clear vegetable oil or mineral oil
- Blue food coloring
- Small star fish, shells and other sea creatures
- One tsp glitter
- White craft glue
- Hot glue
What you do
- Wash and dry two-liter bottle and remove all labels
- Fill bottle halfway with tap water
- Add a few drops of blue food coloring and swirl around to mix
- Add glitter
- Add sea creatures
- Fill bottle the rest of the way with vegetable oil using a funnel
- Be sure that rim and cap are dry, then apply white craft glue around the rim. Seal 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!
