(Drove home from Door County today. Surfing the dial, a couple of great items came over the various channels.)

NPR Report:
A 17 year old student, Ms. Bechtel of Pennsylvania, has invented a device for detecting IED's using sound. How?
She explained in the interview, paraphrased here.
When I was in 8th grade, I was practicing my piano in my room. I am a musician. I noticed the frequencies from the keyboard caused the metal on my banjo hanging on the wall to vibrate. I thought, 'maybe I could use that principle to creat an IED detector using sound.
She used metal tins and authentic IED casings to test it in her backyard. It worked great, other than a few false positives from bottle caps, etc.
She has been sharing her invention in various science fairs and competitions.
I have learned more science from science fairs than I ever learned in school.
Career aspirations? I think she called it a "Molecular Particologist"?, and to work for a company in Sweden.
Wow!

The irony of an classic rock station on Facebook just hit me.
