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.

Great set with easy to do and understand activities

My 4 year-old grandson loves doing these experiments and so do his parents! Great set with easy to do and understand activities. Good quality, good education opportunity. Buy it!

Loads of fun for the kids!

My children are 6 and 9 and they were entertained for hours. The messiness factor is fairly low considering the objects of discovery within this toy. The volcano was nothing like what you would think of from past experiences, but they loved that experiment the best!

It's All In the Box!

Fun experiments at home. My 6 year old really enjoyed them, and he was hands on the whole time. The kit comes with pretty much everything you need. Good learning tool that is also fun! I would buy it again.

Great Family Fun Activities! Exploration and Wonder Abound!

This was a gift for my 4yr old male cousin, 7yr old female cousin, and their parents/my first cousin. I chose it due to familiarity with several of the activities, which students in my science programs and clubs really loved (over the years)! The entire family seemed genuinely delighted to see what was under the wrapping paper. It turns out they had previously used a science set from the same company, and thankfully this box contained different activities. The kids and parents recounted what a BLAST they previously had and how much they were looking forward to diving into this science kit together. They ended up enjoying this set TREMENDOUSLY - claiming nonstop FUN! I will definitely keep this item in mind for future gifts. I'm not certain what the exact directions recommend, but in my opinion this is a kit that absolutely requires adult supervision, if not participation. Fun fun fun!
