Problem: Write an article based on this summary: Check with your vet. Use a flea shampoo to kill fleas. Apply a flea and tick prevention medication to your dog's fur. Treat your house immediately to prevent a recurrence.

Answer: Before using a home treatment, talk to your vet to make sure you get the right product for your dog. Different sized dogs will require different dosages, and young puppies may be too small or young for certain medications. Call or schedule an appointment with your vet to make sure you get the right flea treatment for your dog's specific needs. Flea shampoo is a fast-acting way to kill fleas on your dog. It's a first line of defense, though, and will only last for about a week, so take your dog to the vet for a more permanent oral medication as well. Read over the packaging to make sure you apply the correct amount to the correct areas on your dog. Repeat the bath as recommended by the packaging or your vet. Too much topical flea treatment can be irritating and potentially dangerous for your dog. Be careful about using the right amount for your dog's size and age. Use your flea comb to brush out your dog after they dry to help remove any residual flea eggs. Applying the flea shampoo correctly should leave very little residue on your dog's fur, but still be sure to rinse well afterwards. The same medication that you use to keep fleas and ticks off your dog can be used to help kill a flea infestation. This treatment is more gradual, so it is most effective when combined with a fast-acting treatment such as a flea shampoo. Topical treatments such as Advantage and flea collars can both help manage a flea infestation. Flea collars only target adult fleas. You'll still need to treat your dog with a medication that targets the eggs and fleas in developmental stages, in case any were left over after the bath. Wash your dog's bed, blankets, clothes, and cloth toys in the washer, using dog-safe detergent and the "sanitation" setting if your washer has one. Disinfect bowls and plastic toys with hot water and dish soap. To remove fleas on the floor or carpet, place a flea collar inside your vacuum bag and vacuum up your dog's common areas. Empty the vacuum frequently. Flea-proofing your environment right after an infestation will get rid of any fleas or eggs that happened to fall off and escape.

Problem: Write an article based on this summary: Get a prism. Find a sunny place. Allow light to pass through the prism.

Answer:
There are different types of prisms that manipulate light in different ways. You will need to get a basic prism, also called a refractive prism. This type of prism will allow the light to bend in a way that splits it based on its wavelength. In other words, shorter wavelengths bend more, and longer wavelengths bend less. This creates a rainbow as the light exits the prism. You can buy a prism at a science supply store, a hobby store, or online. Basic prisms are relatively inexpensive. The prism operates by splitting a beam of white light into its component colors. To see this, you will need a high-intensity light source. Put the prism by a sunny window or outside on a sunny day. Make sure that there is nothing blocking the light from reaching the prism. As the light passes through, it will bend and be split into a rainbow. It might be easier to see if you aim the prism at a white wall or a white piece of paper.
