Frequently Asked Questions
Q1: Can I use baking soda instead of Alka-Seltzer?
A1: Yes, baking soda can be used, but it will create a different reaction, so adjust the amounts accordingly.
Q2: Is it safe for young children?
A2: While all materials are generally safe, adult supervision is recommended due to small parts.
Q3: How long does the effect last?
A3: The lightning effect can last as long as the Alka-Seltzer fizzes, typically a few minutes. You can repeat the process by adding more tablets.
Q4: Can I use a plastic container instead of glass?
A4: Absolutely! A clear plastic container works just as well and is safer for younger children.
