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