Olive Oil Lava Lamp
What You’ll Need
16 oz plastic soda bottle with cap
Fizzy Tablet (Alka-Seltzer or Airborne)
Flash light (optional)
1. Fill 1/3 of the bottle with water. Then add around 20 drops of food coloring.
2. Add the vegetable oil till the top of the bottle. Let it remain as such for some time. This is to separate the colored water and oil layers.
3. Break the fizzy tablet into 4 pieces and drop each piece into the bottle, waiting for each piece to dissolve before adding another. Put the cap on the bottle, after bubbling has stopped.
4. Tip the bottle back and forth. Watch for the action! You can hold a flash light under the bottle for an even cooler effect.
