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 activity set!

We bought this set for our 5 year old to do with my husband and mother-in-law during his Spring Break. The instruction booklet lists everything you will need outside of what is included in this set. Each page has a new activity and lists everything you need that's INCLUDED and everything you will need that might need to be purchased. Great set to keep on hand for rainy days or school breaks.

Get to the fun right away !

Love love this set. First I love how easy it is to start. you get 50 experiments which is a great value than you get a very easy booklet with the items you’ll need and clear easy how to do it with pictures and your off! This set arrived at 10pm , normally I would have waited till my kid was asleep to open and “ figure it out “ so she wouldn’t be frustrated but she was so excited that I let her at least open it , than I saw I could quickly do the 1st 2 experiments before bed. We were both happy and I promised to continue the next day . you get everything you need to get started , you may need some additional items but nothing over the top. It’s just right for this non science loving mom and her science loving kid and husband

Great kit

My daughter got this for her 10th birthday and we loved it. We had yet to find a science kit we liked but this one turned out to be great. There are plenty of activities to do with what's included and there is alot included. ( there are also some where you need extra stuff) we made slim, goo, glow worms and dancing bubbles. Instructions are easy to follow and my daughter did most the steps on her own.

9 year old daughter loves it

This is my daughter’s favorite Christmas gift. She has been “playing” with it non-stop since she unwrapped it. Yes, you do need some household items (Elmer’s glue, cooking oil, salt, etc), but the added cost is minimal.

It’s also a set she can use with minimal help from an adult. All I’ve had to do so far (after 9 experiments) is pour some cooking oil and tear off some sheets of paper towel. It’s nice to see her take the initiative and want to try it on her own.

In the interest of objectivity the “50 experiments” is a little misleading. For example you make glow worms in one but the next “experiment” is to leave them out to see what happens.
But I love that no matter what you do whether it’s mixing colors or making a volcano you’re given the scientific explanation of what is happening.
