Frequently Asked Questions:
Q1: Can I use any type of oil?
A: While vegetable oil is preferred, other clear oils like mineral oil can also work.
Q2: What if I don’t have Alka-Seltzer?
A: Baking soda and vinegar is a great alternative. Add baking soda first, then vinegar for a fizzy reaction!
Q3: How long does the lava lamp last?
A: The effects last as long as the reaction occurs, but you can repeat it by adding more Alka-Seltzer as needed.
Q4: Will my lava lamp spill?
A: If sealed properly, it should not spill, but it’s best to do this project in a space where spills are manageable.
