National Geographic Gross Science Kit with 45 Experiments for Kids 8-12 | Brain Dissection, Slime Making, Creepy STEM Projects, Chemistry Activities, Gross Science Experiments, Birthday Gift

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.

This National Geographic Gross Science Kit is perfect for curious kids who love exploring all things weird and wonderful! I got it for my niece and nephew and they loved it! It comes with 45 different experiments, so there’s plenty to keep young scientists entertained. The "gross" factor is definitely a hit—dissecting a brain, making slime, and other fun, messy activities kept the kids engaged and excited to learn. The kit includes clear instructions and most of the materials needed, making it easy to set up and follow along. It’s a fantastic way to spark interest in science and get hands-on experience with experiments. If you have a kid who loves learning about the strange and gross parts of science, this kit is an absolute win!

My 8 year old son loves this. It's a great family activity. Lots of different cool experiments to do. The instructions are easy to follow. The experiments don't take too long. It's super fun and educational. I learned things I didn't know myself 😁

bought for my grandson ... He LOVES it ... he is a six year old all boy and loves to get messy and explore i found it to be the perfect birth day gift

Everything was packed nicely in the box. Instructions were very clear on what materials to use and how much. The kiddos really enjoyed this one

If your child believes the word “gross” actually means “best day ever,” congratulations — you’ve found just the thing! This kit was an immediate hit. Boiling boogers? Glowing worms? Test tube vomit? My daughter was absolutely delighted. I, meanwhile, questioned some life choices… but in a supportive STEM-parent kind of way. What I didn’t expect was how much real science is packed in here. While she was loving the slime and fake bodily fluids, she was also learning about polymers, chemical reactions, and pH. It’s basically a sneaky education operation disguised as chaos. The instructions are clear enough that kids can mostly handle it themselves, which is huge. I supervised, but I wasn’t required to earn a chemistry degree first. Important note: it is messy. This is not a “light a candle and sip tea” activity. This is a “cover the table, roll up sleeves, embrace the yuck” activity. Dress accordingly. Bonus: there are extra experiments using household items, so it doesn’t get tossed aside after one weekend. Final verdict: 10/10 for gross-out joy, strong STEM value, and giving kids the kind of hands-on science experience they’ll actually remember.

Bought it for my friend's kid (with her blessing before) who is obsessed with science & gross things. He unwrapped it at his birthday party and the title is what he said. It’s been a while but I’m still getting updates on how cool each experiment was as they make their way through the box.

Grandson loved it. Great value

My son loves all things science and all things gross, so this was a hit! Allowed him to discover and explore with hands-on experiments. My son is 8 but I’m sure this would appeal to kids of any age. Recommended!

I purchased this Science Kit as a gift for my nephew, and it was an absolute hit. From the moment he opened it, he was completely hooked. Instead of just playing with another toy, he was fully immersed in hands-on experiments that actually made him think. He couldn’t stop talking about what he was learning. The experiments kept him engaged for hours. It wasn’t a one-and-done activity, he keeps going back to try new experiments. If you’re looking for a gift that’s exciting, interactive, and actually sparks curiosity about science, this is it. It’s rare to find something that makes kids this enthusiastic about learning. Five stars without hesitation.

I gifted this for my 7 yr old nephew and he loves this science kit. It's a great family activity where he gets to spend time with his parents. His parents have thanked me as they feel it was a great gift and tell me my nephew appreciates it

got this for our son (age 7) for Christmas. he loves doing the science experiments with us. discovering the reactions with the various items in the box was pretty neat even for us adults. you have to do the experiments in the order they are in in the book as some products you make are needed for other experiments. I do wish the pictures in the book looked more like the actual outcome of the experiment, my son was a little bit disappointed. overall love it and will buy different boxes.

I bought this for both my partners son age 11 and my niece age 6 they both absolutely loved these experiments and had a blast 💥 with every single one in the box. Fun for the whole family and you learn some things. Would definitely but more and different types of sets.
