9 year nephew loved learning that energy doesn't always come from a battery

Complex enough to engage kids but not frustrate them. The grandsons have received 6 of these kits and they love them all. They are simple to build and fun to play with. Affordable price. A nice project for child and parent if they are too young to build byj themself

I was looking for projects for my kids to pass the time this summer, I thought these would be the perfect thing. My issue with this product is that it’s missing a lot of the items needed to complete the project, which is big bummer.

It's a bunch of flimsy plastic pieces, and the experiments don't work that well.The cloud maker barely works at all (we tried quite a few times, and it was almost noticeable twice).The water cycle thing had the wrong piece for the base so it was very hard to put together, and didn't have a hole in the mountain at all (which is referenced in the directions), so I ended up cutting one in the wrong place because there was no indication of where it was supposed to have been, and then when we followed all the directions it kept flipping over in the water. I finally filled the base with stones to weight it down, and even then the water cycle really wasn't apparent.So it definitely did not feel like value for money. Disappointing.

Grandson loved this project and he learned so much

Worked great! The kids loved it. And it kept me from having to go on a scavenger hunt through various lumber stores in attempts to create a DIY potato clock. Great for our lesson.

Easy to assemble.

Gave it as a gift to my grandson

Ok so the finished robot is TINY, see photo above. About two inches tall.The science is very cool, we enjoyed building the battery. I had to use google to look up how a magnesium air battery works as the explanation on the leaflet said little about that.My 9 year old was unable to do most of the work: it required adult strength to force the pieces to clip together (and work out the confusing leaflet instructions). So as a solo project to amuse a child it failed dismally. As an interesting performance for an adult to show a child, it did well.Would expect to pay £7-15 for this type of product.

I couldn't believe how light the box was when it arrived, it was seriously like it was empty. It could have come in a matchbox. We got it made and it ran once and that was it. What a terrible rip off. Almost fifteen pounds … and for nothing. It really doesn't deserve even one star

Birthday present for a 9 year old boy

My Grandson loved it.

Mes enfants ont été très déçu par ce kit. Mal élaboré, trop cher pour ce que ça vaut.
