black toothpaste is healthy & refreshing

Image
Last week a friend asked me in the morning if I had ever used black toothpaste. Since I had never even seen black toothpaste, I notified of my ignorance towards such exotic commodity; and later out of curiosity I did a search on the Internet. No wonder I did find it in Japan, a place of varied and exotic ideas! It seems that Kobayashi Seiyaku, a pharmaceutical company has been selling black Sumigaki toothpaste since 2003.It turns out that Sumigaki toothpaste is made primarily out of charcoal - or carbon, that effectively helps in removing plaque, eliminates bad-breath, prevents tooth-decay and stops cavity; and the mint flavour refreshes your mouth. Besides, the carbon present in the charcoal actively whitens your teeth. Its chemical composition is that of water, phosphoric acid, charcoal, glycerin, cellulose, and a few other compounds.After nine years, this toothpaste is still a hit in many countries, and the only reason is that Sumigaki has been able to interpret black as a colour o…

identify a single voice among the crowd

Professional footballers beware: the argument you are having with your coach could soon be overheard even within the cacophony of a packed stadium. A new microphone system allows broadcasters to zoom in on sounds as well as sights, to pick out a single conversation. Physicists Morgan Kjølerbakken and Vibeke Jahr, formerly at the University of Oslo, Norway, were working on sonar technology when they came up with the idea for what they call a supermicrophone, now dubbed the AudioScope. The device is made up of around 300 microphones arranged in a fixed circular array above the sports ground. They are used in conjunction with a wide-angle camera that can zoom in to any position on the pitch. Because the camera is also fixed, it can be calibrated to zoom in to any location within its range. The AudioScope software then calculates the time it would take for sound emanating from that point to reach each microphone in the circular array, and digitally corrects each audio feed to synchronis…

a very interesting little old lady

A little old lady goes to the doctor in the city, and says, “Doctor I have this problem with gas, but it doesn’t bother me too much… my farts never smell, and they’re always quiet. But I’ve been doing it very often.”The doctor asks her to explain more, and the old lady says, “In fact, I’ve farted at least twenty times since I’ve been here in your office. You probably didn’t know I was farting because they don’t smell and they’re silent.”The doctor says, “I see, take these pills and come back to see me next week.” The next week the lady comes back. “Doctor,” she says, “I don’t know what the heck you gave me, but now may farts… although still silent… sink terribly.”The doctor says, “Good!!! Now that we’ve cleared up you sinuses, let’s work on your hearing.” Technorati Tags: ,,,,,,,,,
