Ok, another wunderkind story. At the age of 11: * Knows how to program Arduino * knows how to write Android Apps * has a working understanding of chemistry * is able to infuse carbon nanotubes with chlorine and build a disposable sensor from this. * understands marketing enough to promote her product via the app stores (there really is no other reason for using a smartphone instead of three colored LEDs to display results). Is anyone really buying this? Here's a more likely story: * Parents see scientific curiosity in her daughter, as well as the will to help people. * Parents see a fear of lead in water and therefore a market for testkits * Parents see that testkits already on the market suffer from being unreliable in untrained hands/too difficult to use. * Parents have the idea for a better, "digital testkit", but that turns out to be way more expensive than anything that is already on the market. * Parents then spoonfeed the idea to her daughter. They do the work, she gets the credit (and probably thinks that she did most of the work). * The media picks the story up because "awwwww ... smart kid", resulting in free marketing for what would otherwise be a totally overengineered/overpriced product.
