## Description

desertcart.com: National Geographic Gross Science Kit - 45 Gross Science Experiments- Dissect a Brain, Make Slime, Creepy STEM Project for Boys and Girls, Birthday Gifts for Kids 8-12 (desertcart Exclusive) : Toys & Games

Review: One of his favorite gifts - I bought this kit for my little brother, and honestly, it was a huge hit. From the moment he opened it, he was really excited to see everything included. His favorite part was definitely the “gross” experiments because, of course, that is the best thing ever to a 10-year-old. I liked that it not only kept him entertained but also made him curious and ask questions about how things work. Definitely a great gift choice.
Review: Super fun and educational - Fun experiments. Perfect fit for ages 6-10. Brings everything you need (I had to get a lab coat lol). Instructions easy to read and understand with images included.

## 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.
