[color=DimGray]In the Dec., 2006 photomicrograph released Thursday, May 29, 2008 by The Nakao Hamaguchi Laboratory of the University of Tokyo, a "carbon nanotube ramen" in a bowl with diameter measuring one-thousandth of a millimeter (one-25,000th of an inch) produced by the university's mechanical engineering Prof. Masayuki Nakao and his students in a project aimed at developing nanotube-processing technology is shown. "We believe it's the world's smallest ramen bowl, with the smallest portion of noodles inside, though they're not edible," Nakao said.

Mechanical engineering professor Masayuki Nakao said Thursday he and his students at the University of Tokyo used a carbon-based material to produce a noodle bowl with a diameter 1/25,000 of an inch in a project aimed at developing nanotube-processing technology.
The Japanese-style ramen bowl was carved out of microscopic nanotubes, Nakao said.
Nanotubes are tube-shaped pieces of carbon, measuring about one-ten-thousandth of the thickness of a human hair.
Carbon nanotubes are being explored for a wide range of uses in electronics and medicine because their structure endows them with powerful physical properties such as a strength greater than steel.
The ramen bowl experiment included a string of "noodles" that measured one-12,500th of an inch in length, with a thickness of one-1.25 millionth of an inch.
"We believe it's the world's smallest ramen bowl, with the smallest portion of noodles inside, though they are not edible," Nakao said.
The hardest part was to keep the noodles from rising upright from the bowl "like alfalfa sprouts," he said. "The achievement was mostly for fun."
The microscopic bowl was first created in December 2006, but revealed only Thursday after it was entered for a microphotography competition last week.

日本打造最小面条碗 直径只有万分之一厘米
据美联社报道，日本科学家用先进的纳米技术打造了一个微型面条碗，小得只能在显微镜下才能观看它。
日本东京大学的机械工程学教授中尾真之今年5月29日表示，他和他的学生用碳纳米管材料制造了这个直径只有2.5万分之一英寸(1万分之一厘米)的面条碗，其目的是开发纳米管加工技术。此日本式的面条碗是由微小的纳米管雕刻而成的。碳纳米管直径只有我们头发丝的一千分之一，由于它具有比钢还结实等强大的物理特性，科学家正在将它广泛用于电子学和医学领域。
此面条碗里还装有一些"面条"，面条长度只有1.25万分之一英寸(5千分之一厘米)，厚度仅为125万分之一英寸(50万分之一厘米)。中尾真之说："我们认为它是世界上最小的面条碗，里面装有最小段的面条。"打造此碗最难的工作是让面条悬于此碗当中，看起来像紫苜蓿芽似的。
此微型碗最初于2006年12月制造，但直到5月29日才公诸于众，因为它上周参加了一项微型照片竞赛。

也有概念炒作的嫌疑啊。。。小琬可能会有用。。。方便面也有用。。。可是非要放在一起。。。。有啥用？
