    It was the perfect rainy day project as it kept my daughter occupied and learning.

    I have been obsessing over Kiwico for months and finally ordered some of the items that managed to arrive all the way to the UK in good nick. My son is a wee 5 year (below the suggested age group for this item) but understands the concept of ‘hydraulics’ because we subscribe to Mel science boxes catered to 5 year olds and one of the box was about hydraulics. Both my son and I were impressed with the contents of the box and how it is such a layered project - so you don’t finish the project as soon as we finish building one thing. The book that came in the box is good too. He has been inventing his own contraptions and seems to enjoy himself while playing with his invention. I look forward to buying more things from kiwico store but they seem to have limited items that can be shipped to the UK which is a shame.

    My son liked this project but it was difficult to get it connected to the box & to make it fully functional. Still his 2nd favorite project
