You can get creative with the type of container or bottle you use.

What you will need:

• Vegetable oil (or get a clear oil)
• Water
• Food coloring of your choice
• Alka-Seltzer Tablets(as many as you choose, the more the merrier!)
• Clear container (the taller and skinnier, the better the effect)

4 Easy Steps:

1. Fill the container with 2 parts oil, 1 part water, leaving some room at the top of the container for a little bit of bubbling
2. Drop in a few drops of food coloring
3. Add an Alka-Selzer Tablet, start with 1/4 or a half a tablet to begin with
4. Watch is fizz and bubble up to the top!
