  This is a "feel good" human interest story, not a scientific breakthrough. As someone who worked as a chemist in a lab for a long time, this is a nice classroom demonstration of chemistry, but in no way an actual scalable solution (using calcium phosphate to trap lead? we have way better way to do that).

    Thing is I wouldn't want any of the people from the project to see this thread. This is exactly the wrong way to discuss project work of young people. At that age what to a grown adult seems like mild criticism can seem 1000x worse to the person. This is easily an area where HN should not tread at all if it can't get that right.
