Spooky Lava Soda

Even the grouchiest ghoul can’t resist the glow of this DIY lava!

• 3 tablespoons ARM & HAMMER™ Baking Soda
• Vegetable oil
• Vinegar
• Food coloring
• Tall bottle or cup
• Small container or cup
• Spoon

1. Add 3 heaping tablespoons of Baking Soda to a large empty bottle or tall cup. (Hint: It’s easier to see the bubbles move in a tall container!)
2. Fill two-thirds of your tall bottle with oil. The Baking Soda will stay on the bottom of the container; do not try to mix it with the oil.
3. In a small cup, add enough vinegar to fill the remaining third of the bottle and three drops of food coloring.
4. Add drops of the colored vinegar to your tall container and watch your homemade lava lamp bubble.
