    • One of his favorite gifts
Style: 45 Gross Experiments
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. ... show more

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 😁

    • Quality time spent with grandkids
Style: 45 Gross Experiments
My grandkids ages 2 through 10 had a lot of fun doing the experiments and learning from the information that accompanied the directions. The only warning is that most of the experiments we did were dependent on other experiments. Still, good time spent with the grandkids
