The Face The Software Gotcha! Lots More Information A ticket to Super Bowl XXXV in Tampa Bay, Florida, didn't just get you a seat at the biggest professional football game of the year. Those who attended the January 2000 event were also part of the largest police lineup ever conducted, although they may not have been aware of it at the time. The Tampa Police Department was testing out a new technology, called FaceIt , that allows snapshots of faces from the crowd to be compared to a database of criminal mugshots. Photo courtesy Visionics Facial recognition software can be used to find criminals in a crowd, turning a mass of people into a big lineup. The $30,000 system was loaned to the Tampa Police Department for one year. So far, no arrests have been made using the technology. However, the 36 cameras positioned in different areas of downtown Tampa have allowed police to keep a more watchful eye on general activities. This increased surveillance of city residents and tourists has riled privacy rights groups. People have an amazing ability to recognize and remember thousands of faces. In this edition of HowStuffWorks , you'll learn how computers are turning your face into computer code so it can be compared to thousands, if not millions, of other faces. We'll also look at how facial recognition software is being used in elections, criminal investigations and to secure your personal computer.

And this lotion base has been developed using a different technology, so it's easy to use to create your recipes. Most lotion bases are pre-blends of water, oil, and emulsifying wax. Using emulsifying wax requires that the formula be heated to melt the wax and create the O/W bond. Those lotion bases tend to have a wax-like feel due to the emulsifying wax and often create drag on the skin and pilling after a second application. The viscosity (thickness) in your final product is adjusted by the amount of water and additives you include in your final formulation (which might mean a lot of tweaking!). Lotion Base CM is a totally cold process product because it does not contain waxes which need to be melted. The lotion base kit consists of two products: Lotion Base CM - a water-thin cream base and, Polymer SP - a cosmetic grade thickener, which has been pre-mixed with an emulsifier. No wax or alcohol! Your product is simply made by mixing 10% Lotion Base CM with 90% water (Distilled), which makes for a very cost effective formulation. After these two ingredients are blended, you can add up to 5% vegetable oils. Next, the thickener concentrate, Polymer SP, is added to your blended lotion base at levels of 3% - 9% to achieve a viscosity from very thin, like a body mist, to very thick, like a night cream. Finally, incorporate your preservatives, color and fragrance. Youve got a finished product in three easy steps! Yield: 1 Gallon Lotion Base CM makes 10 gallons of lotion 1 Quart of Polymer SP will thicken 10 gallons of lotion Lotion Base CM Pricing Starter Formulation WE SUGGEST ALWAYS STARTING WITH STERILIZED METAL OR GLASS BOWLS & METAL MEASURING & MIXING TOOLS, WORKING ON A COUNTER SPACE CLEANED AND WIPED WITH A LIGHT SOLUTION OF BLEACH IN WATER. We suggest using a digital scale to measure your components. Choose the batch size you wish to make from the table below. Set your scale for either ounce or gram measurements. Measure your ingredients in the quantities listed in either ounces or grams. Remember, all measurements are listed by weight, not by fluid ounces. Phase 1: Pre-mixing the Lotion Base CM Ingredients: Quart Batch 1/2 Gallon Batch Gallon Batch Oz Grams Oz Grams Oz Grams Water (Distilled water @ room temperature) 28 784 56 1568 112 3136 Lotion Base CM 3.25 91 6.5 182 13 364 Vegetable Oil (Sweet Almond, Olive, Apricot Kernel) 2 48 3.25 91 6.5 182 Preservative: Germaben II .35 oz 9 .70 oz 19 1.40 oz 39 Mix these products together for 2-3 minutes using gentle agitation with whisks or mixing spoon. The oil and water will not emulsify, but you want the mixture to be well blended. Phase 2: Preparing the Polymer SP Stir your container of Polymer SP well before portioning. Choose the amount of Polymer SP to add to your Phase 1 preparation, using the Consistency Table below to choose the end product you wish to make. IMPORTANT: You can always add more Polymer SP to increase thickness, but if you start TOO THICK, you will need to prepare another Phase 1 batch to re-balance your desired viscosity. So if you are not sure, add increments of the Polymer SP to achieve your desired consistency. PRODUCT CONSISTENCY TABLE (PER ONE GALLON BATCH) Add 3 oz Polymer SP for a very light lotion Add 5 oz Polymer SP for a normal lotion Add 7oz Polymer SP for a very light cream Add 9 oz Polymer SP for a night cream Phase 3: Blending Your Recipe Slowly pour a stream of your Polymer SP portion into your Phase 1 base, while continuously blending (a stick blender works well). You will notice the lotion start to thicken after mixing for about 2 minutes. Continue mixing for a full 5 minutes to ensure that Polymer SP is completely dispersed to activate the emulsifier and the thickener. When youve achieved your base consistency, add your preservative (listed in table above) , color and fragrance , and blend well. Your ready to package!

soap solution, thesoap films

Exploratorium: Science Snacks: Soap Bubbles Soap Bubbles Create geometric art with soap films. ######### -- ######### -- Using pipe cleaners and drinking straws, you can makethree-dimensional geometric frames: cubes, tetrahedrons, or shapes ofyour own design. When you dip these frames in a soap solution, thesoap films that form on the frames are fascinating and colorful. Plastic drinking straws. Pipe cleaners (available at school supply, hobby, or party stores). A small bucket or container for the bubble solution. The container must be large enough so that bubble frames are entirely covered when they are dipped. Bubble solution (You can use a commercial solution like Wonder Bubbles™, or use the Exploratorium's recipe: To each gallon (3.8 1iters) of water add 2/3 cup (160 ml) of Dawn™ or other dishwashing liquid and 1 tablespoon (15 ml) of glycerine, available at your local pharmacy. Bubble solution works best if it is aged at least a day before use.) (30 minutes or less) Form frames using the drinking straws for the straight pieces. Connect two straws at a corner by inserting a doubled pipe cleaner into the end of each straw. In places where three straws meet, fold the pipe cleaners as shown in the diagram. Attach a pipe cleaner handle to your frame. Try constructing cubes or tetrahedrons, or just let your imagination run wild. Mix the soap solution in the bucket. Make sure that you have enough solution to fully cover the frames when they are dipped. (15 minutes or more) ######### -- Dip the frames into the soap solution, and observe the fascinating geometrical shapes that the soap films form. Also notice the shimmering colors in the soap film. As you lift your frame out of the solution, the soap film flows into a state of minimum energy . The soap film is in a state of minimum energy when it's covering the least possible amount of surface area. The intricate shapes you see inside the frame represent the minimum area the soap film can cover. You may notice that a soap film will sometimes take on different shapes when you dip the frame into the solution again and again. That's because there may be more than one way for the soap film to form a minimum surface area. When light waves hit the soap film, they reflect and interfere with each other. This interference causes the shimmering colors you see. White light is made of many different colors. When white light shines on the soap film, some light waves reflect from the front surface of the film and some reflect from the back surface of the film. When these two sets of reflected waves meet, they can add together, cancel each other out, or partially cancel, depending on the thickness of the film and the initial color of the light. When light waves of a particular color meet and cancel each other, then that color is subtracted from white light. For example, if the red light waves cancel, then you see white light minus red light, which you perceive as blue-green light. Plastic bar straws, which have a smaller diameter than regular drinking straws, hold the pipe cleaners more tightly. But bar straws are more expensive and are sometimes harder to get. If you can't find them at grocery or liquor stores, try restaurant or party supply stores. Questions? Comments? Want to share your results? Join the: Like this snack?
