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 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.

My son is 9 and definitely has a knack for building things. This took about 1 1/2 to assemble. He was engaged and wanted to make sure everything was perfect. The instructions were clear and precise. The build quality is great. There is zero leakage from the launch mechanism. The functionality is spot on. Overall, great value for the cost. He had so much fun building it and is now having fun launching anything he can get his hands on.

Fairly easy to assemble, even for someone less than handy. No screws or glue, my six year old and I enjoyed putting this together, he played with it a lot for a few weeks as expected he lost interest after a while but the experience was rewarding.

This was a gift for my grandson, he really liked it. The experiments were awesome. A cool gift, lots of fun.

It's very easy to make the experiments.

Well made parts & project!!! Directions were easy to follow & went together as expected. Exceeded my expectations, leaving my boys with many hours of fun so far. Well worth it!!!

I bought this for my seven year old grandson, him and My Husband spent probably an hour and a half putting this together, one of the very best gifts I have ever purchased We have been in the engine and construction business forever, and this interested my grandson in engineering just because of the way that he had to help put it together. It is absolutely a five star model.

NOT IN THE DESCRIPTION .... This is a rubber band shooting game! **The model itself is great, but I'm giving 3 stars for the lack of transparency in product advertising. Body: Lots of pieces, labeled alphanumerically. Not for little kids, but a nice challenge for school-agers. Gun: User-built. Uses rubber bands to shoot flat/round plastic discs. Cards: Decent factoids about a handful of organs (brain, heart, lungs, liver, kidney, stomach, intestine). And four germ cards that I suppose are to be used if you're playing card game style. Overall, a good project for little learners. Bonus points for the opportunity to explain eyeballs when your kid shoots his brother's out.

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!

This is a fantastic present for my kid's 9th birthday. He was able to follow all the instructions. He loved to see all the different mechanisms involved and how it works at different stages. The final result was lots of pride and lots of fun playing with it. Really good quality.

This is an awesome product.

Not so interesting toy. The assemble of the whole structure especially the gun is difficult for children. Final idea of the product is to hit the viruses with the gun, which might lead to risk and accident because using the gun might not be always to the body.

view: This science kit is very good for kids. It keeps them engaged for a long time and helps reduce screen time. The activities are fun, hands-on, and educational, so children do not get bored easily. It encourages curiosity and learning while playing. A great way to keep kids busy and away from mobile phones.
