Ingredients
Method
- Pour the oil into the jar until it is about two-thirds full.
- In a separate cup, mix the water with a few drops of food coloring.
- Slowly pour the colored water into the jar so it sinks in beads beneath the oil.
- Add a few drops of dish soap if you want the drops to move more slowly.
- Break an Alka-Seltzer tablet into small pieces and drop one piece into the jar.
- Dim the lights and hold a small flashlight to see the streaks like lightning.
- When the fizz stops, add another small piece to restart the motion.
Notes
Keep the jar capped when not in use and store at room temperature. Use caution with Alka-Seltzer around young children.
