I think it is amazing how Arvind Gupta came up with so many different ways to teach kids different methods of design and different scientific techniques through toys made out of trash. This is a huge breakthrough because there are children in schools throughout the world who do not have enough money to get a proper education, and this man has created a way to further facilitate the learning process for these kids in a very cheap manner. Some of the future's greatest scientific minds may be in schools that do not even have a roof over their head. Therefore, it is our job to come up with ways to teach these kids, like Arvind Gupta did, through cost-efficient means.
