6. Frequently Asked Questions
Q1: Can I use a glass bottle instead of a plastic one?
A1: Yes, a glass bottle works perfectly, just ensure it’s not too heavy to handle safely.
Q2: What if I don’t have Alka-Seltzer?
A2: You can substitute with baking soda and vinegar. The reaction will be slightly different but still fun!
Q3: Why does the food coloring sink?
A3: Food coloring is water-based, which is denser than oil, causing it to sink until it combines with the water.
Q4: How long will my DIY lava lamp last?
A4: The initial reaction will last for several minutes. You can keep adding Alka-Seltzer or baking soda and vinegar to reactivate it.
