how does stripe toothpaste created? when you squeeze the container, it's always stripe output. It doesn't mix.
831539
The stripes were created by a special device that was fitted to the nozzle end of the tube: a tube within the tube, if you will, about one inch in length and perforated with a ring of small holes around the top. \n\nToothpaste tubes are normally filled from the flat end, which is then folded over and sealed. In the case of Stripe, a red toothpaste was first filled around the special fitting; the white toothpaste, filled second, held the red toothpaste in place at the top of the tube. \n\nWhen the tube was squeezed, the white toothpaste would run through the special inner tube, while the pressure of the squeeze simultaneously forced the red toothpaste through the tiny orifices at the end. With the flow of red matched to the flow of white, the toothpaste emerged from the nozzle perfectly striped.

use a toothpaste with baking/bicarbonate soda in it.\n\nWhen you use it, it feels slightly gritty, and it don't taste too good, but it does work really well if you use it twice a day for a couple weeks (sometimes less)

Please, the question is not completed because if you are try to use separating techniques , you must have a mixture that you want to separate so toothpick is just a substance and not a mixture you can add any other substance before it become a mixture.\nthanks for my mark.

The suds in your bubble bath aren't entirely white. They do have a slight amount of color from the soap, but it's so small it's hard to notice. Actually, all things that create bubbles experience this same phenomenon. Beer, soda, and detergents all produce bubbles that are considerably lighter than the liquid they came from.\n\nBubbles are composed of a thin spherical film. The film is both translucent and reflective so some of the light that is hitting the bubble is absorbed, but most is reflected. The small amount of light that is absorbed gives the color of the bubble, but the majority that is reflected takes the color of light around it which is usually white.\n\nWhen you mix any color with white it gets lighter. Because soaps have only a little dye they are easily diluted. Colas however have a dark caramel color, which is why their bubbles appear tan.\n\nTo alter this you can replace all your light bulbs with green tinted ones and your bubble bath will turn green.

You are on the right track. It relies on inductive charging:\n<quote>\nIf you own an electric toothbrush, there's a good chance that it has a completely sealed toothbrush unit. The toothbrush rests on the charger without any metal contacts to connect the toothbrush to the base. This has the great advantage of allowing the toothbrush to be completely sealed so that water cannot enter through exposed contacts. It also avoids any problems with water getting into the contacts and shorting out the charger.\n\nThis sort of sealed arrangement is called inductive charging. Essentially, the toothbrush and the base form a two-part transformer, with the base having one part of the transformer and the toothbrush having the other. When you slide the toothbrush onto the base, the complete transformer is created and charge can flow.\n\nThe base contains one of the coils and the metal bar. The toothbrush contains the second coil. When you drop the toothbrush onto the base, you create the complete transformer!\n</quote>

It takes energy not only to break up the solid solute into its individual particles, but also to force the solvent molecules apart.  Now, if the solute can offer the solvent some very attractive forces (like sodium ions and chloride ions do from table salt) the whole process will work. The energy required to break up chalk is just too great.

YES!!!! It still has phosphoric acid in it which is the main cause of demineralization of a tooth (decay process).  If the soda has sugar in it then the sugar takes over in the demineralization process in the areas that the acid did prior.  I have seen so many people, esp kids w/ a lot of decay inbetweeen their teeth from soda...any kind!! Gaterade and Kool-Aid are other big no gos when it comes to teeth

toothpaste r filled upside down , in which two or more equal pressure nozzles r filling the tube. then another machine closes the tube , so they will not mix

Okay toothpaste sounds scary... what if the color stays under the diamond... then it continues to look dirty... I have been told to use liquid soap with a toothbrush and rinse with warm water.....  THat is what my jewler has suggested and it seems to work great.  Good Luck and be careful with the toothpast, its made for teeth!

It works the best with "Wintogreen," rather than peppermint, and should be done with a fresh pack (the moisture makes it spark better). The spark that comes from the Life Saver is considered as a type of triboluminescence, which the sugar in Life Savers contain. Here's an excerpt from my source site: \n\n"Wintergreen sparking, it's believed, is actually a three-step process. Step One: When you shatter the sugar crystals with your teeth, electrons (which are negatively charged) break free. As a result, the atoms in which the electrons were formerly embedded become positively charged. In what amounts to a subatomic game of musical chairs, the free electrons dash around madly trying to find a new home.\n\n"Step Two: Meanwhile, as the sugar crystals disintegrate, nitrogen molecules from the air attach themselves to the fractured surfaces. When the free electrons strike the nitrogen molecules, they cause the latter to emit invisible ultraviolet radiation, along with a faint visible glow.\n\n"Step Three: The UV radiation is absorbed by the wintergreen flavoring, methyl salicylate. This then emits the fairly bright blue light you see. Pretty complicated, I admit. Clearly the planners in the Pentagon weren't the first to be obsessed with high-tech gimcracks."

I know you said excluding toothpaste, but have you tried the new Luminous?  I was in the same boat, and it was suggested to me, and I am very happy with the results!\n\nSorry!

The samples must be homogenously ground to enable the solvent to fully soak into the sample and extract the compound you want in question. Also there is a question of statical averages so a uniformed powder sample is the best for this process. If the sample is lumply or too big the solvent can't fully soak into it and wherefor not all of your compound in question is extracted by the process (Then the solvent fills up the soxhlet thumbie (sp)). If this happens you will get a incorrect value then you come to do the maths in determinating the amoult of the coumpound in question.

Whitening toothpastes will not change the shade of the teeth. At best, they may do a little better at removing some of the extrinsic stains on teeth caused by such things as smoking and drinking dark beverages.... doing these every day things is what cause your teeth to discolour. I would not recommend using them because they are abrasive and could potentially damage the tooth's enamel. \n\nThere are no strips, gels, etc that you can purchase over-the-counter that have been approved by the ADA (American Dental Association), therefore, I do not recommend the use of them. The only products approved by the ADA can only be purchased through your dentist. You should also be under the care of your dentist while you are using a tooth whitening program because the dentinal tubules are opened up during the process which can sometimes cause extreme sensitivity in the teeth. Your dentist would know when to discontinue use of the product.

We started our search by typing some of the better-known toothpaste brands into our browser's location window. We tried www.crest.com, www.colgate.com, and www.mentadent.com and received some information on the various types of toothpastes, what they do, and how they do it. However, we were ultimately unsuccessful in finding the basic toothpaste ingredients. \nRealizing our quick approach was ineffective, we went to the old standby and typed "toothpaste ingredients" into the Yahoo! search box. \n\nAs expected, Yahoo! didn't have a Toothpaste Ingredients category, but our search wasn't a waste -- we received thousands of web pages that featured the words "toothpaste" and "ingredients." We were on our way to a clean and sparkling answer. \n\nWe clicked on the BDA Facts File, a subpage of the official British Dental Association web site. We scrolled down to find a list of active and inactive ingredients that may be included in toothpaste. \n\nActive Ingredients: \n\nFluoride \nAntibacterial agents, most often Triclosan is used to control plaque \nDesensitizing agents \nAnti-tartar agents \nSodium bicarbonate (baking soda) \nEnzymes, to enhance the antibacterial properties of saliva \nXylitol, a non-sugar sweetener, which reduces levels of cariogenic (decay causing) bacteria in the mouth and enhances remineralization \n(Natural toothpastes may contain a variety of ingredients - anything from oil of ginger to seaweed extract.) \nInactive ingredients: \n\nWater \nDetergents, to make the toothpaste foam \nBinding agents \nHumectants to retain moisture \nFlavoring, sweetening, and coloring agents like peppermint, spearmint, cinnamon, wintergreen, and menthol \nPreservatives \nAbrasives for cleaning and polishing \nWe clicked on another link, this one an article from WebMD titled "What Are You Putting on Your Teeth?" The article explains that almost all toothpastes start with mild abrasives and detergents, as well as the near-universal ingredient, fluoride. After that, toothpastes vary quite a bit. \nPossible ingredients include: tartar-control agents, most often pyrophosphate; sensitivity reducers, such as potassium nitrate; triclosan; baking soda; and teeth whiteners. \n \n \nEmail this page - View most popular \n   Related Links \n\nCopyright © 2000 Yahoo!

It was indeed "Pepsi Clear" and it was tasty, although definitely different than Pepsi.\nI wish it had succeeded, though: the caramel coloring on colas builds up on your teeth, whereas clear cola should have no such problem.
