INPUT ARTICLE: Article: You need fresh, white carnations to do this experiment. If you try to use a darker color, you won't be able to see the change as much. If you already have white carnations in your garden, cut a few to color. You can buy white carnations at any florist and in most grocery stores, too. When you cut the flowers, leave at least 6 inches (15 cm) of stem. Consider the size of the vase that you are planning to use to display your flowers when cutting your carnations. You need a vase or cup for each color you want to use. Shorter will probably work better than taller. If you want red and yellow carnations, you'll need two vases. Fill up each vase about 1/4 of the way with water. Next, add in food coloring for each color you want to create. You'll need a lot of food coloring to get an effect, at least 15-20 drops. You'll need more if you want them darker. Once you have your vases ready, you'll want to cut your flowers again. Cutting the flowers again allows them to draw up more of the colored water. It's best to cut the flowers under running water or underwater because that keeps the flowers from getting air bubbles in their stems, which block the water. To create carnations that are multi-color, you must split the stem in half with a craft knife or box cutter. Split it down the middle lengthwise, being careful not to cut your fingers. Only adults should do this step. You may also be able to split it three ways, if the stem is especially thick. Gently pull the stems apart at the bottom. Slip one part of a stem into one cup and the other part into another cup. Make sure you do not separate the bottom stems from the flower or break the stems higher up. The cups should be right up next to each other, so you don't have to spread the bottom stem apart too much. Now, you must wait, as this process takes time. You'll need to wait at least a day for the color to develop. In fact, color will continue to develop over the next several days if you leave it in the colored water. You may only see parts of the flower petals changing color, not the whole petal. Cut flowers continue to soak up water to create food for the flower. If that water is colored with food coloring, then the color will spread to the petals. If those petals are white, then they'll turn the color of the food coloring.

SUMMARY: Buy or cut some white carnations. Create your vases or cups. Cut the carnations. Split the stems. Place each piece of stem in a different cup or vase. Leave the flowers.


INPUT ARTICLE: Article: For some pets, such as guinea pigs, it is not possible to use many of the flea treatments available. In this case, a simple bath may be your only option. By bathing the pet in warm, not hot, water, you're trying to drown the fleas. This won't likely kill any eggs left, and it may be necessary to comb your pet, as well as repeat this bath.  Since the fleas will run to the head and face of your pet once you start wetting them, it is best to wet and lather up only the neck first then the rest of your pet. This will create a barrier to prevent the fleas from invading your pet's face and ears. Use room temperature or slightly warm water, so as not to shock or harm your pet. Stop the bath with small pets that get too stressed out. Animals like rabbits and guinea pigs can die from fear-induced heart-attacks. Though it may cause some skin dryness and/or irritation, dish soap can be effective at killing fleas. The soap is toxic to fleas, and can be used as a way to control the infestation. Make sure to rinse your pet thoroughly. These are shampoos that are specially designed to treat fleas in specific animals. Find one formulated for your pet. Make sure to follow the instructions provided exactly, to prevent any injury to your pet. Always rinse thoroughly. Residue from flea treatments can irritate your pets skin, and possibly lead to harm. By taking the time to rinse all the soap, shampoo, or herbal treatment from your pet, you will help to remove fleas, as well as ensure leftover residue doesn't cause your pet more discomfort.

SUMMARY: Use just water. Use dish soap in a bath to kill fleas. Get a flea shampoo. Rinse thoroughly.


INPUT ARTICLE: Article: The type of boomerang you buy will have a significant impact on whether you will get it to come back to you or not. Boomerangs are made from regular pieces of wood or plastic, so it takes some skilled workmanship to imbue such everyday materials with the aerodynamic qualities that make boomerangs so unique. There are loads of boomerangs on the market, but not all of them are true returning boomerangs, so do your research before you buy. Pick one that is made from lightweight materials. These boomerangs do not require a strong throw, which allows beginners to focus more on technique. They will usually travel between 10 to 25 meters (32.8 to 82.0 ft) before returning. Be aware that you will need either a left-handed or right-handed boomerang depending on your dominant hand. If you're left-handed, you will have considerable difficulty in throwing a right-handed boomerang with any success.

SUMMARY: Purchase a high quality boomerang. Beginners should choose a v-shaped or a tri-bladed boomerang. Pick a boomerang made for your dominant hand.


INPUT ARTICLE: Article: You can either use fresh lemon juice, or lemon juice from a bottle. The lemon juice will be added to the jar along with the tomatoes. The juice helps to prevent the tomatoes from spoiling while they are in the jars, and also helps to retain the color and flavor of the tomatoes. Place the jars on a heat resistant surface and begin spooning the quartered tomatoes into the jars. Fill the jars until there is only about ½ of an inch of space left at the top of the jars. Add two tablespoons of lemon juice. You should also add either boiling water or hot tomato juice so that the jar is filled up to ½ an inch away from the top. You could also consider adding other ingredients to enhance the flavor of the tomatoes. Cloves of garlic, peppers, or a sprig of basil make delicious additions to canned tomatoes. Once you have added the lemon juice, gently press on the tomatoes with a spoon to release air bubbles. Air bubbles are bad because they can let bacteria get into the jars, thus spoiling your canned tomatoes. You should also slide a sterilized knife or plastic spoon along the inside wall of the jar, releasing any air trapped there. Place a lid on top of the jar and screw on the band with your hands.

SUMMARY:
Choose your lemon juice. Fill the jars with the tomatoes. Remove any air. Wipe away any drips along the top and sides of the jar.
