Student working with nanotechnology equipment in the clean room

In SEH, a scaled-down ?teaching clean room,? shows students the ins and outs of building devices at the nanometer level, a space about 100,000 times smaller than the width of a human hair. In this room, air is scrubbed of containments like hair and dust, which can easily destroy experiments, and researchers must put on head-to-toe ?bunny suits? before entering.
