Smartivity DIY 2in1 Hydraulic Paper Airplanes & Darts Launcher STEM Toy for Kids Ages 6-14 Years I Birthday Gifts for Smart Kids | Science Kit for Boys & Girls 6, 8,10,12,14 Years Old

This kit was fun to make with my grandson. All the parts were there, the instructions are clear and easy to follow, and the end product is cool and also engaging to play with. It's a great analog toy that encourages scientific inquiry, fun to see how the hydraulic launcher comes together and works.

This was a complicated build for a 6-year-old, but it is interesting and works well. It comes with several paper airplanes that can be folded, but also works with nearly any paper airplane you make. Also shoots nerf style darts. The hydraulic aspect of the build is a particularly nice and educational addition.

This was a great gift for my 6 year old’s birthday. It took us a couple hours to put together with me mostly helping him learn how to understand and follow directions compared to what he was physically doing. Directions were nice and easy to follow. The launcher worked great once put together and my 6 year old was really proud of what he created at the end.

My nephew LOVES this so much. Got it for him for Christmas and he has had a blast with it. Great value. Might order one for my husband because it looks so fun!

This was a lot of fun for my son to build and he loved it at first but now it’s just a display for the most part. Maybe when the weather gets better he will use it more. I would much rather buy something like this that he builds than for him to watch tv. The parts moved just as advertised and overall, I would buy something like this again.

I got this for my 8-year-old grandson for Christmas. This is a very well made project. Sturdy parts so no worrying about snapping of a piece of something while assembling it. The parts are held together with various sizes of very small rubber bands. A couple of them were a bit tricky to put on, and I had to help him a few times. The instructions are very clear and easy to follow. It works well once it is completed. My grandson was really fascinated with the hydraulic action and especially loved shooting the nerf missiles all over the house. I am writing this in March, and it hasn’t fallen apart yet ! If you have a Lego builder, this will be very enjoyable for him or her!

This was such an awesome gift for my 8 yr old. He loved building it, with a little help of course. I wasn’t sure how this thing would work, but it is great. It shoots extremely far and has kept my son busy playing with it for hours. Highly recommend

Bought as a gift for my 9yr old nephew. He loved it and was able to put it together himself. Pretty cool little project, worked like it was supposed to, I would buy again.

Well designed and good quality toy. For the price it is simply worth it. The packing and quality are outstanding. The instructions are well illustrated, the parts are numbered in order for easy assembly. The final assembled toy works as advertised and is fun to play with. For younger kids the assembly may be little daunting but parents can help out as well. For those parents who still harbour the inner child, this kit is simply a blast!

My 7yo loved this. He needed a bit of help in the assembly at first but once he got used to to the rubber bands ( used to attach the pieces) he cruised through it alone. It really works and he learned a bit about hydraulic power. Would definitely order again!

Excellent. Our 7 Yr old grandson built this no trouble. It works brilliantly

Good activity for kids , it’s fun assembling the kit and good learning . Overall good. My 7 year old liked it

This is an EXCELLENT product. Very good instructions and build is quite complex. Got it for my 5 year old too difficult for him to assemble but very fun to play with supervision. Amazing for older kids for sure. Bravo !
