This story of the thinnest needle reminds me of a story one of engineering professors used to tell many years ago. A US toolmaker had a healthy competition with their Japanese counterpart. The US company one day announced that thay had created the world's tiniest drill bit - almost as thin as the human hair. The director of engineering packaged and mailed one of the new bits to their Japanese competitor.
A few weeks later a package arrived at the doorstep of the US firm - containing the drill bit that they had sent. Inspection under a microscope revealed that a hole had been neatly drilled through the center.
What would Neil Young write?
"I (barely) see the needle/
And the damage done..."
But when you drain them in a collander, won't they slip out thru the holes? Oh, thats Needles, sorry......
