1 Hour : Play It : Waves In A Bottle

While you're telling your kids about the Mayflower, you can help them create their own "ocean" a bottle.

Use a clean dry bottle with flat sides. Fill one-third of the way with WHITE VINEGAR; add several drops of blue FOOD COLORING. Fill the rest of the way with a light-colored COOKING OIL like canola. Screw the cap on tightly, and then rock the bottle back and forth to watch the waves. Oil droplets are lighter than those of the vinegar, so they float to the surface and stay there. The two never mix, even when you tilt the bottle.
