A lot of folks sent this in today, a 17 year old made a sub-$1,000 spectrograph. If anyone knows more about this and/or is in contact with Mary let us know!

A 17-year-old girl won a scholarship worth $100,000 for building an inexpensive yet accurate spectrograph that identifies the “fingerprints” of different molecules.

Mary Masterman, a senior at Westmoore High School in Oklahoma City, was named the winner Tuesday of the annual Intel Science Talent Search.

More than 1,700 high school seniors across the nation entered the contest, which is in its 66th year.

Spectrographs, which measure wave lengths, are used in research such as astronomy and medicine and in industry. For example, they can be used as a sensing device to look for explosives or drugs or to help determine how old an art work is through its pigments.

They can cost as much as $100,000, but Masterman’s invention — made of lenses, a laser, aluminum tubing and a camera — cost less than $1,000, Intel said.
