Cover with water and let simmer for 20 minutes. Use a large spoon to skim any foam that rises to the top and continue to simmer for 5 to 10 minutes. Remove the stock from heat, strain, and set aside to cool. Any fat content will congeal on top of the stock when cooled, and can be scooped-off the surface with a spoon and discarded. Reserve or discard the fat as preferred.

On the homepage, click on the orange "Submit a Free Ad" button. You will be taken to the ad creation page. Here is where you enter all of the details of your ad. Follow the prompts to enter all of the relevant information. You will be prompted to create a title, write a description, upload pictures, quote a price and enter your location and contact information. Make the title appealing. Think of descriptive keywords related to your item that people would use to look for that item. Include the item's brand name or designer if applicable. Include the size, color, and condition of the item in the title. State specifically what the item is in the title. Suppose you are selling a beaded bracelet. Think of all of the terms buyers might use to search for this bracelet. For example, they may be looking for a new or antique bracelet, a certain color, or a specific metal finish. Add all of that information in your title. Make your title read something like this: "New Handmade Beaded Bracelet Silver Pink Pearls." This way, your listing will come up whenever a buyer enters any combination of those terms in a search. Avoid using acronyms or all caps in your title. Categories include mobile devices, computers, cars, furniture, pets, books and fashion, among others. Many buyers search by category. So it is important to choose the category that best fits your item. If you're not sure what category to choose, try searching for similar items and seeing what category other sellers have used. Make your description as informative as possible. List the most important information first, such as the size, shape and color and the item's condition. Add information about what's included with the item and the kind of packaging. Never say something that isn't true. Also, keep the tone positive and avoid negative comments. Try to think of any questions to buyer might have and answer them in the description. Using the example of the bracelet, you could write the following description: "This bracelet was handmade in a smoke free, pet free studio. It features round, pink and white pearls, connected by sterling silver links. The lobster clasp allows for adjusting the bracelet to fit on any size wrist. The length is 6 inches." Set a fair price for the item. The price should reflect the item's condition. Prices that are too high will drive away potential buyers. Conversely, prices that are too low make buyers question the quality of the item. If you are not sure how to price your item, look for similar listings of items in comparable condition. See what those sellers are charging for their items. Note that the price must be set in the currency of the country where the ad is placed. You can add up to eight photos of your item. If you are using the website, upload photos from your computer. If you are using the app, select the photos from your smartphone that you want to include with the ad. Add enough pictures so that potential buyers can get a good look at the item. Take pictures from several different angles. If possible use, outdoor lighting. If you can't use outdoor lighting, be sure to use enough indoor lighting to adequately show the item. Ads with more pictures get more responses from potential buyers. Submit your name. Then, enter a phone number you want buyers to use to contact you. Also, enter the city where you are located. This way buyers know where they have to go to find the item. For safety purposes, don't include your home address anywhere in the listing. Choose the city that is closest to your location. Since transactions happen in person, buyers need to know where you are located. Some buyers who don't live nearby may ask you to ship from your location. You will have to decide for yourself whether or not you want to do that. You may wish to change the selling price to include shipping. Make safety a priority when choosing where to meet. Make sure to meet in a public, well-lit area near security cameras, if possible. A good example of such a place is a police parking lot.

Believe it or not, plain old tonic water glows under a black light quite brightly, as well. To get this effect, start by pouring some tonic water into a container where you can see it. You can add it by itself or dilute it with water. However, the more water you add, the dimmer it will glow. Tonic water is available at most local stores and supermarkets for just a few dollars. Be sure to get tonic water, not club soda or soda water. The bottle should say "with quinine" or something similar. All you need to do to get tonic water to glow bright is to illuminate it with a black light. Be sure to dim the lights in the room before you do this or it will be more difficult to see the glowing effect. Black lights are available from specialty party stores (like Spencer's, etc.) or online. The price for the black light often depends on its size and brightness basic lights can cost as little as $20 or less. Making tonic water glow with a black light makes it look very strange, but it doesn't make it poisonous, radioactive, or harmful to drink in any other way. However, tonic water is often high in calories and sugar, so enjoy it sparingly. Tonic water glows this way because of tiny chemicals called "phosphors" inside the liquid. When ultraviolet light from the black light (which humans can't see) hits the phosphors, they convert it into a form that humans can see, producing the glow.
