Wave tanks use liquids with two different densities that won't mix together. Here's an easy, non-toxic method.

Difficulty: Average

Time Required: Minutes

Here's How:

  1. Add water, oil, and food coloring to a clear container.
  2. While this works well in a bottle, consider using an aquarium or plexiglass tank with a windshield wiper motor to get real wave action.

Tips:

  1. I'm told that windshield wiper motors are available from American Science Surplus, JerryCo, or JC Whitney.
  2. Other liquids will work equally well or better. Choose liquids with different densities that won't mix.

What You Need:

  • Oil (vegetable oil, baby oil, etc.)
  • Water
  • Food Coloring
  • Clear Container
