Mine detector No 4A, with battery case, headset, cables, and canvas holdall. From the collection of the National Army Museum, London:

The assault troops landed on five beach areas, supported by airborne landings on the flanks. Among the problems they encountered were the five million mines planted by the Germans along the Normandy section of the 'Atlantic Wall'. Mines of all types were scattered in belts of varying thickness on the beaches, across fields and on roads. The intention was to make landing so difficult that the Germans could counter-attack the Allies while they were trapped on the beaches.

To counter this threat, mine detectors were supplied to Field Companies of the Royal Engineers, Pioneer Corps, and Pioneer Battalions of the Infantry Divisions. When held about 10 cm above the ground, the detector plate created an electro-magnetic field. When this met a metallic object an impulse was created, and by means of the amplifier, made a sound in the headphones of the operator. To counter this the Germans later developed mines of non-metallic materials such as wood, bakelite, and even glass - making them ruthlessly efficient and responsible for many Allied casualties.

Meet Marian Bechtel. She's a 17-year-old pianist, scientist, 2012 Intel Talent Search finalist, and passionate anti-war activist. Oh, and a normal high school student in Pennsylvania.

Bechtel invented a low-cost device that can act as a prototype for a new type of mine sweeper. Using sound waves to determine where explosives are located, the device is a standard metal detector equipped with microphones and a seismic vibrator. Her idea came about when she played certain notes on the piano and noticed that the strings of a nearby banjo would vibrate -- she then decided to investigate whether the same principle could be applied to detecting landmines in warzones.

Bechtel's project was also inspired by her parents' work in geology. "Years ago they got connected with an international group of scientists working on a project called RASCAN, developing a holographic radar device for detecting land mines," she told MSNBC. "I met all of these scientists and talked with them about their work and the land mine issue. I was really touched and inspired by what they had to say."

Marian was in good company with her fellow Intel Science Talent Search 2012 finalists. Seventeen-year-old grand Prize winner Nithin Tumma won $100,000 for his pioneering breast cancer research. And although she didn't win, finalist Samantha Garvey, a homeless New York high school student, won a $50,000 scholarship, appeared on "The Ellen Show," and was invited to hear Obama speak at the White House.
