## Description

desertcart.com: NATIONAL GEOGRAPHIC Mega Slime Kit & Putty Lab - 4 Types of Slime Plus 4 Types of Putty Including Magnetic, Slime Kit for Boys and Girls, Sensory Toy & Science Kit : Toys & Games

Review: Huge hit for a 4-year-old — messy fun, tons of variety, and surprisingly educational - I bought the NATIONAL GEOGRAPHIC Mega Slime Kit & Putty Lab as a Christmas gift for my 4-year-old nephew, and it ended up being one of his favorite presents. From the moment he opened the box, he was completely locked in — bright colors, fun textures, and lots of hands-on activities kept him entertained for hours. First off, I really love how much variety comes in this kit. You get multiple types of slime and putty, including magnetic putty, which instantly became the “wow” factor for him. Each texture feels different, so he didn’t get bored moving from one activity to the next. One minute he was stretching slime, the next he was poking putty or watching the magnetic pieces move around. For a kid with a short attention span, that variety makes a big difference. What surprised me most was how easy the instructions were to follow, even for younger kids with adult help. Everything is laid out clearly, and the steps are simple enough that my nephew could participate instead of just watching. He loved helping mix things together and seeing how it transformed into slime — it really felt like a mini science experiment rather than just a toy. The sensory aspect is fantastic. This kit is great for little hands: squeezing, stretching, poking, rolling — it keeps them engaged and helps with fine motor skills without feeling like “learning.” It’s playful, creative, and calming all at once. He especially loved comparing how each slime felt different and proudly showing everyone his creations. I also appreciated that this feels more thoughtful than a typical slime kit. It leans into the science side just enough to make it feel educational, which made me feel better about gifting it. It’s not just screen-free entertainment — it encourages curiosity, experimentation, and creativity. Yes, it can get a little messy (it is slime), but that’s part of the experience. With a table covering and supervision, cleanup was totally manageable. Everything stayed contained, and nothing stained or ruined surfaces, which was a big relief. The quality of the materials feels solid, and there was plenty included to make multiple batches. It didn’t feel skimpy or like a one-and-done activity. Even after Christmas day, my nephew kept coming back to it over the following weeks, which tells me it has real replay value. Of course, this definitely works best with adult supervision at this age, especially during mixing and handling smaller pieces — but as a shared activity, it’s wonderful. It turned into bonding time, learning time, and playtime all rolled into one. Overall, I’m really happy I chose this as a gift. My nephew was thrilled, the parents approved, and it provided hours of hands-on fun that didn’t involve a screen. It feels like one of those gifts that actually gets used instead of forgotten in a toy pile. Highly recommended as a Christmas or birthday gift for young kids — engaging, creative, sensory-rich, and genuinely fun for both kids and adults.
Review: Quality product with good price - My niece totally loves these kits! Great quality and lots of activity for a really good price.

## Questions & Answers

**Q: Do the slimes come already made or do you make them ?**
A: Our Mega Slime & Putty Lab comes with 7 pre-made mixtures and 1 packet of Red Slime Powder for performing one's own experiment

**Q: Is the slime/putty gluten free? Wheat free? Thanks in advance.**
A: There is no wheat or gluten in our Mega Slime and Putty

**Q: Is there latex in any of these ingredients?**
A: I opened it up as I havent wrapped for Christmas yet and though many warnings about how harmful and dangerous the chemicals can be,,not one word advising what the ingredients are.....Luckily I,m giving to 13 yr old grandson..because outside the box it warns to not give to children under 3 due to small parts..Inside it warns not to be used by children under 8 and no matter what age, adult supervision is advised during experiments.

**Q: Can the color changing putty change to other colors?**
A: Yes but it takes long. I felt it was a waste of money in my opinion. I gave low review :(
