National Geographic Gross Science Kit Chemistry Toy for Ages 8-12 | Brain Dissection, Boiling Boogers, Gooey Guts and Slime, Gross Chemistry Experiments, STEM Projects, Birthday Gift

I got these to do fun project over summer break with my 9 and 10 year old boys and they had a blast! Especially if your kids are sensory seeking, its a big hit!

They mean it when they said gross. My grandson , 10 years old, loved it.

Horrible horrible instructions. This is for a child. The instructions should be easy to read. Why don’t you try a number system in order. I’m shocked that National Geographic has their name on this chemistry set.

Got for my best friend’s boys. Haven’t given it to them yet, but I’m excited to see them use it!

Grandson is really enjoying doing the different experiments! Got it for him for his birthday

Perfect to keep 2 grandsons occupied

This was a huge hit with my two kids. They had a blast with it right away, an I was really pleased with how long it engaged and stimulated their minds!It managed to be gross in the fun way kids actually enjoy, but still felt like they were learning something while doing it. They were excited to open everything, read through the directions, and jump into the experiments which were very thoughtfully designed.A few of the activities definitely got some laughs from the kids and then me, especially the more slimy sounding ones, but they were also paying attention and asking questions the whole time.It’s a really nice mix of science and entertainment and ideal for those around 5-10, but I had a blast too. The kit has enough variety that it didn’t feel repetitive, and both of my kids were able to get involved instead of just watching. That made it a lot better than some of the other science kits we’ve tried.Very happy that they grew and had their minds stimulated as well as how much fun they had doing it. Great value for hours of fun.

While this entertained my kids for an hour or so, I was less than blown away by it. The experiments mostly revolve around dropping one chemical into a different one to make gel-like substances of different colors, which you can call "boogers" or "blood cells" or "brains" and then pop or scoop.I felt it needed a lot more variety. The educational aspects, meanwhile, are mainly a few facts scattered in the instructions.As a pro tip, if you do the experiments out of order, read the whole instructions first to make sure the one you're doing doesn't rely on something made in an earlier one. My kids wanted to do the brain first, which involves a cool mold, but then partway into it we realized we needed to go back and make the blood cells to drop in.This isn't a bad buy, necessarily, but I feel like it doesn't live up to its potential, either for science or for entertainment.
