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

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.

My niece totally loves these kits! Great quality and lots of activity for a really good price.

This was a hit at Christmas. It has all different types of slime, putty, etc. and we only played with it in the kitchen to avoid any accidents. No glitter, no confetti, just the goo 🙃

A big heat at the girls party!

My boys love this and it’s easy to clean up and actually very educational as well. And it’s pretty clean. The texture is different on all of them. Pretty good variety as a well. My boys love the glow in the dark one as well.

Quite a hit with children; variations of slime types; magnetic, glow in the dark, and more!

My nephew will absolutely love it. Great slime quality not too runny . Lots of colors to experiment with.

Love this so cute! love the stuff that’s included so much variety and great for gift! the package is fun and exciting great overall and happy with it

Ordered this as a gift for my kid and its a blast. different slimes and puttys that are fun to experiment and play with plus a slime to make yourself. Highly recommend for kids of all ages!

I bought the Mega Slime and Putty Lab for my 9-yr old (who is obsessed with making slime / putty) and it was the greatest purchase ever! 8 different kinds, all in individual jars - they amount you receive for each is generous as well. My daughter is always watching YouTube videos on how to make different types of slime - but sometimes you're unsure if it turned out 100%. With this kit, she now knows how different types of slime / putty are supposed to look and feel - it's a fantastic reference for those who enjoy making their own slime. Also, there's a great little book that comes with the kit as well explaining all of these different slimes / putties - you cannot go wrong with this purchase!

Good way to explore the different types of slime /putty. The magnetic putty is ok but it’s not that magnetic. The powder slime included, once “done” only lasted 3 days in its container before becoming more a gooey smelly substance. All the other slime and putty are pretty fun, for kids and adults.

This was a gift for my 7 year old and she LOVED it. It came with many different types of slime/putty, and she was fascinated with all of them. They are all very long lasting, EXCEPT for the bouncy slime. It dried up after a while and turned into a hard foam, and we werent able to stretch it out anymore. But all in all, this box of slime was great! I would definitely recommend it!! Makes a great gift.

When the National Geographic Slime Kit and Putty Lab arrived, my grandchildren grabbed it out of the couriers hands and tore open the box. They were ecstatic and played with the slime and putty all afternoon. They especially loved the magnetic putty with a real magnet and the oozie, gooey slime that ran through their fingers. All the slime and putty were in separate tin containers which the children took great care to put them back into. The booklet that comes with the kit has fascinating facts about slime in conjunction with nature. Which National Geographic is famous for.
