Our SmartKidsPlanet initiative began in 2017 when 3 geeky and dedicated parents saw a gap in the children’s toys and games market. An opportunity was spotted while we struggled to find toys and games for our kids which enriched their minds and guided them toward science, art, math and construction. The trio then knew that their paths were set, establishing an online shop with a comprehensive range of intelligent toys for babies, children and young teenagers.

With offices based in California, our SmartKidsPlanet team enjoys a daily growth in our presence within the children’s educational toys market. We love our new place in life, and we love helping young minds with their growth and skill development, all while having as much fun as possible.

Fun and colorful

My daughter just turned 9. She loves this set. She loves that it۪s so colorful and easy to perform messes...I mean experiments haha! She doesn۪t really get the science behind the experiments though and that۪s the only thing I wish they could build into these sets.

Fun and easy for young children

My grandson absolutely loves this. He's mixing colors and learning how they work. We have a budding artist.

Nice kit - everything included - messy!

My kids enjoyed this kit a lot and it was easy to do all the experiments with what's in the box and no other supplies. I'd recommend doing the slime activities outdoors.

A superb science-oriented set

I love, love, love this toy! I chose to review it because I have a third grade cousin on whom I could test the set, and it was a hit in every way. The experiments are well designed, and the instructions are easy to follow--something I think is extremely important. I also love how easy it is to clean up after you are finished--everything washes up easily. You will need a few extra items for some of the experiments, but most homes will have these things around--things such as baking soda and vinegar. This set claims to produce 50 experiments, but some of these are variations on one another, so I would say 25 is closer to the truth. Still, that is a lot for the price.As a retired teacher, I appreciate well-designed toys that offer learning experiences as well as play, and this toy does not disappoint. It is perfect for those long days of summer when your child is bored. Parents will need to be involved, especially for younger children, but to me that is a plus. For the price, this toy cannot be beat. And it may give your child an idea or two for the school science fair! Highly recommended.
