According to the News.ninemsn.com on February 9, a video posted on YouTube shows a US man has created a helmet capable of shaving a person's head in a matter of seconds.
据国外网站 "the News.ninemsn.com" 2月9日报道，YouTube网站一段视频显示，一位美国男子发明了一种可以理发的头盔，只需几十秒，就可以瞬间剃头。

The helmet device injects shaving cream and operates four razors simultaneously, and appears to provide a clean, tidy and safe haircut in 20 seconds.
头盔装置中注入剃须膏，并有4个刀片同时运作，只需20秒就可以理一个干净、整洁的光头，安全可靠。

"When you shave your head manually you move back and forth and laterally, which is what the helmet is doing right now, times four," said the inventor Boris.
理发头盔的发明者Boris指出：“当你手工剃头时，你得前后左右来回移动，而这顶头盔的剃头效率是手工剃头的四倍”。

At the end of the process, the volunteer in the video has a closely-cut shaved head with no sign of cuts or scratches.
在最后，网络视频中那个胆大的实验者没有任何割伤和刮伤的痕迹。
