This was one of the first inventions from FutureReadyKids and it took a lot of time. Getting this right got us the confidence that kids can find real life problems and build real solutions. For the first time, we saw kids producing "non-academic" material. 

The iterations were too many. Constantly figuring out what was going wrong and finding solutions, importing clips from China, selling this were all an adventure. Now you can buy this on Amazon(click, buy, use and please give feedback)

Here is a video of how I invented it. 

And this is a small video of how to use it.
