Solar Marble Run & STEM Projects for Kids - Science kits for boys & girls -3D Puzzles for Adults & Kids,Prefect Physics Toy and Engineering Activities for Kids - Model Kit for Science Experiments

As a tween girl who loves engineering kits and Kiwi Crates, it is bothersome that this kit is classified as a STEM toy for boys. This kit was curated by a tween girl who loves engineering kits and Tinker Crates. This kit was a good mix of being easy to follow instructions and taking a fair amount of time. You don't want one that takes forever or goes by too fast. I saw no signs of frustration or boredom from her. The marbles we had bought were too big to fit on the track/through the gear holes so we bought more. In that case, you would have to look for a slightly smaller size if you wanted If I had young children or pets that might come into contact with them, I would be cautious.

What a great kit this is. Putting the event together took us less than an hour. As we were assembling it, some of the pieces seemed a bit flimsy, but once it was constructed, we were surprised at how sturdy it turned out to be. My favorite part of it is that it has the option of solar or battery power. There were only a few steps on the instructions that I couldn't understand, so we had to go back a couple of times to change parts to face the other way.

I gave it 4 stars instead of 5 because some of the instructions were unclear.

During a recent family gathering, I purchased this kugelbahn kit so my 13 year old son and 9 year old niece could have a little fun. Despite a little help from Dad, they were able to complete the project by themselves (okay, once he helped out). As they followed the instructions and assembled the pieces, it was wonderful to watch them work together. When handled with care, the wood pieces become extremely fragile, but with a bit of patience, they can be popped out and snapped together. Honestly, I was surprised at the quality of the end result. I was skeptical that it would work the first time I tried it. My first thought was that the main wheel would get stuck or marbles would fall from Not at all! As soon as we exposed it to the sun, those marbles started This is one of the reasons why I think the experience of putting it together alone is worth the price. It's like a jigsaw puzzle in that regard. Having a really cool piece of mechanical art at the end of it is an added bonus.

We had a lot of fun painting and creating this marble maze with my second grade class. As groups of two or three, we took it in turns to paint and assemble it. Several of the parts had to be assembled with the help of an adult. Because the first spiral part broke, I was very thankful it came with a spare spiral. Kids who enjoy putting together models would definitely find it a great gift. Homeschoolers that are working with small groups of students would also benefit from it.

A seller who cares about STEM is easy to spot. Smarts Toy is one of my favorite brands. They come up with the most It is my second time purchasing from you. The gift was purchased as a birthday gift for my niece who is 9 years old. Since I haven't opened it yet, I haven't read it When my niece lets me know about the review, I will update The book will be a big hit with her.

This kit is really awesome. This supply has extremely low stipulations. As soon as we began working, we broke the small gear because I was not careful with how I cut the connecting My life was turned upside down. I noticed the kit came with an extra set of gears, which I didn't expect! A fragile piece of the ramp is also part of the ramp. The event was a success. A battery-operated version of the device has been completed and tested. It would be great to try it on solar but we can't wait for a sunny day. This is a highly recommended book.

The amount of time I spent doing this was greater than what my 11-year-old Even though assembly was straightforward, the instructions weren't too clear, and the glue was more like Elmer's glue than There was no way to hold the pieces in place. In order for the ball to enter and circulate, we couldn't line the ramp up appropriately. Similarly, the machine stopped working when it got stuck.
