A German scientist created a soccer field so small 20,000 of them could fit on the end of strand of human hair.
The University of Kaiserslautern's Stefan Trellenkamp used nanotechnology and one day's time to engrave a soccer field's lines on the minute pitch of acrylic glass. The field measures 500 by 380 nanometers and can only be seen with a special microscope. One nanometer is a billionth of a meter or 0.00000003937 inches.
"I am really, really proud," the researcher told Reuters by telephone. "The only problem is that I really don't know what to do with it. I can't put it on show as no one can see it.
"I guess it'll just stay in my drawer for the time being."
