    Love tinker crate!

    My son that this was great and every member of our family loved it and tried it! His 15 year old brother, 13 year old brother... His 17 year old sister and yes no and dad we all liked it. He even took it to school to share... He is in 4th grade and did it 100% by himself... So yay! I liked it so much, we got a 3 month subscription for our friends son as a birthday present and I think they will continue monthly. They too loved the gravity game!

    good quality

    I liked the quality of the crate, this game has been a blast and will never get old it keeps me busy for a long time if I'm bored I always love the joy of opening a new crate to see what it will be!

    Fantastic activities!

    It is science based, which my kids love. And I love the booklet that comes with it, helping me and my kids understand and explain the science behind the gravity game. This kit is fantastic

    really engaging

    Loved that this was simple to put together and provided continued entertainment. Really engaged my son. The cones to demonstrate what was happening with the center of gravity were a great addition to explain the concept.
