Los Angeles Science Teacher suspended over student science fair projects

An anonymous reader writes: "A high school science teacher at Grand Arts High School in Los Angeles was suspended from the classroom in February, after two of his science fair students turned in projects deemed dangerous by the administrators. " "One project was a marshmallow shooter—which uses air pressure to launch projectiles. The other was an AA battery-powered coil gun—which uses electromagnetism to launch small objects. Similar projects have been honored in past LA County Science Fairs and even demonstrated at the White House."
