Watch Fermilab's Astoundingly Massive Neutrino Detector Being Built

The Department of Energy's Fermilab is building a gargantuan detector to examine uncharged subatomic neutrinos that can blast through the earth unimpeded. The 14,000-ton detector in Minnesota will capture neutrinos shot from a cannon over 500 miles away . Watch how they build a huge catcher's mitt for subatomic particles.
