Wave Maker

Supplies Needed:

• Plastic soda bottle-2 liter, clear and empty
• Vegetable oil
• Blue food coloring
• Water

Instructions:

1. Fill soda bottle half way with water.
2. Add drops of food color to desired color.
3. Twist top on and shake to mix food coloring with the water.
4. Add vegetable oil to fill (all except about an inch on the top).
5. Seal bottle tightly with cap.

For Fun:

• Swirl the bottle while it's standing up or lay it down on its side and rock back and forth to create "waves."
• Try creating large bubbles by turning the bottle top over bottom a few times.
• Create tiny bubbles by really shaking it up.

Special Note:

The oil may get a little cloudy when you've been playing with your wave maker a lot. Just let it sit still for several hours or days and the oil will eventually return to normal.
