After six months of diligent testing, three schoolgirls in a Palestinian refugee camp have developed a revolutionary walking cane that could help the blind better avoid obstacles and navigate stairs. The girls' accomplishment comes as a beacon of hope in their impoverished refugee camp.

Known as "stick-tech," their invention has won them admission to the Intel International Science Fair in California.
