laboratory

I have heard about 3D printers and am amazed at what they can make, but have never understood how.  When I read that they now have a printer that can make a pizza I decided it needed to be researched further and turned to the Fab Lab at Denfeld High School and the instructor, Kevin Chederquist for answers.

The quietest place on the planet is in Minneapolis, MN at Orfield Laboratories.  That's where they have built an anechoic chamber that is 99.99% sound proof.
