Wave Maker

What You Need:

• Clear, plastic bottle (at least 10 inches high)
• Denatured alcohol
• Blue food coloring
• Vegetable oil

Instructions:

1. Fill the bottle three-fourths full with the denatured alcohol.
2. Add blue food coloring (make it a deep blue color).
3. Fill the bottle with cooking oil, leaving a small space at the top.
4. Glue the top on for safety. The substances will not mix and the water will move like a wave over the oil when moved up and down.

Note:

Get an adult to help with this activity if necessary.
