Adult Supervision Required...

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

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.
