## Questions & Answers

**Q: Is there a way to purchase just the two mixing packs to make the lava?  The coloring in the mix pack is far better than I can reproduce.**
A: Just baking soda and vinegar… look it up

**Q: What is the quality of this item?**
A: I think it is a really nice product.  Plenty of experiments.  Some are repetitive, using the same ingredients to produce a slightly different product. Like making a volcano erupt, making it erupt bubbly and making it erupt loud.  My 6 year old enjoys it.  He has to be supervised though.

**Q: Are extra Instruction manuals available online?**
A: Please contact us directly at help@natgeotoys.com for instructions assistance.

**Q: How can I replace the magic kit I've already ordered witj the Stunning science kit**
A: You would need to go through the return process and then order the Stunning Science Kit.  Unfortunately, we do not have a way to adjust orders.

### ⭐⭐⭐⭐⭐ Great science gift!
*by N***A on January 2, 2026*

We had 2 hours of fun. Made 5 of the things in one sitting and my son who is 7 said he loved it and had fun. Great way to spend quality time with your kid or just if you’re a science lover it’s fine for adults too I think. Everything is safe except the microwaving part which asks you to have an adult.
