What I liked Tons of activities, kept my kids busy for hours. The “dissect a brain” kit was their favorite. Instructions are clear and easy for kids to follow. What I didn’t like Some experiments are very messy—prepare your table! A few items feel more like toys than real science. My experience My 9-year-old loved making slime and showing it off. It turned into a fun family activity. Final verdict Perfect gift for curious kids who like gross stuff. Just make sure they’re ready for cleanup afterwards.

Nephew - 7 absolutely loved it! I did a few of the experiments with him. Easy & fun! Had a blast. Some were a bit messy too, but worth it! The only one we had trouble with was making the eye balls! Otherwise they all worked great!

Kept my autistic son busy for at least seven hours. Definitely needs adult assistance, but totally worth every minute of bonding time.
