INPUT ARTICLE: Article: It will be easier to remove the stain with chemicals and water if you first scrape off whatever toothpaste will loosen up. Try using a small knife or sharp object to scrape off as much of the toothpaste as you can. If you are a child, only do this with parental supervision, however. Scrape only very gently so that you don't end up damaging the clothing by poking holes in it. You are just trying to get the surface-level toothpaste off. Be careful not to rub the toothpaste too hard or you could embed it even more in the fabric. You could also try to use your fingers to pick some of it off if you are nervous about using a knife. The sooner you try to remove the toothpaste, the easier it will come off. If the toothpaste sits on the clothing for very long, it could erode the color in the clothing. Whitening toothpaste that contains bleach can damage the clothing especially if it remains on it for very long. Many stain removal methods involve water. You need to make sure the fabric won't be damaged if water is applied to it. If the clothing is dry clean only, do not use water at all or it will leave a spot. If you don't have time to take the clothing to the dry cleaner, there are dry cleaning stain removal products that can be used on these pieces, though. This will help loosen the stain some more. Mix a few drops of laundry detergent with a cup of water. You can use stain remover in place of the laundry detergent. Try spot cleaning the clothing first. Dip the cloth in the sudsy water, and gently blot/scrub the toothpaste area. Once the detergent penetrates the toothpaste stain, the stain should release itself somewhat. Wet the area and put pressure on your shirt with the water so it comes out. If it still looks tinted white, then it is not completely out. The titanium dioxide powder causes the white staining on clothing. That's why you will likely need detergent to get it out. Blot the area with water to rinse. Allow the spot to air dry. Don't apply heat to it yet because heat can set the stain into the clothing. It's possible that this is all you need to do. It depends on the nature of the stain. If the stain remains at all, you'll have to wash the clothing more thoroughly.

SUMMARY: Scrape as much of the stain off as you can. Check the tags on the clothing. Moisten a soft cloth with warm water, and blot the stained area.

INPUT ARTICLE: Article: Any microscope will do, but a compound microscope is the best kind for observing microscopic, transparent specimens, such as dust mites. You can buy a compound microscope online or from a retailer that sells them to schools, hospitals, and research organizations. You can also acquire a cheap microscope with a 10x magnification lens from a toy store, hobby store, or thrift store. You need to use at least 10x magnification when viewing dust mites under a microscope. Using a clear piece of tape, pick up clumps of dust from surfaces such as shelves or the floor. Put the tape on the slide under the lens of the microscope with the power set to at least 10x magnification. Dust mites are 0.3 millimetres (0.012in) in size, so they can't be seen with the naked eye. Use a lint-free, microfiber cloth to handle the slide to avoid getting fingerprints on the glass. Carry the slide between your thumb and forefinger by its sides rather than by the top and bottom. The stage is located at the front of the microscope under the objective lenses. It's a flat, square platform with metal clips on it for holding slides. Gently lift the clips and close them over each end of the slide to hold it in place. Don't force the slides under the clips, as they are fragile and can be easily broken. A power switch on the bottom controls the light. Use the dimmer switch by pushing it forward and backward to adjust the lighting. Adjust the light intensity to low with the dimmer switch at the bottom right of the microscope. When you turn the microscope on, increase the light intensity to a level that isn't too bright or too low. A ring-like object called the diaphragm lets you control the amount of light that reaches the specimen. You can rotate this with your hand to adjust the amount of light under the specimen. It's located under the stage. You can rotate it by simply turning it with your fingers. This is the level at which dust mites can be seen. If the dust mites are still out of focus, increase the power objective until you see them clearly. They have long hairs along the edges of their bodies and short hairs all over their bodies. They don't have eyes or antennae. Under a microscope, you'll see dust mites crawling all over one another. Dust mites' mouths resemble heads.

SUMMARY: Obtain a compound microscope with 10x magnification. Collect samples of dust and put them on a slide. Put the slide under the stage clips. Plug in the microscope to turn on its light. Rotate the nosepiece to the 10x power objective. Look for clear, oval-shaped arachnids with rigid bodies.

INPUT ARTICLE: Article: It can be hard to catch a girl's attention if she thinks you have other commitments. Don't spend a lot of time hanging out with other girls in a one-on-one setting. Consider mentioning that you're single around her, but don't force it into conversation or say it in a way that is self-pitying. Mention how you wish you had something fun to do on a night you're free. Your friend isn't going to make the move while you're out with your friends getting fast food. Figure out something that the two of you can do together alone. Don't do something dramatic like taking her to a fancy restaurant. Something as simple as going to the park together is fine. Let her know that you are interested. Flirt with her a little bit. If you aren't sure how to do this, just smiling and laughing a lot while you have a conversation is a good place to start. Don't do it too much or it will seem forced, but doing it more than usual will let her know you are really enjoying talking to her. Playing hard to get isn't going to work. Be open and honest with her. Give your honest opinion if she asks you what you think about something. You don't have to wear your heart on your sleeve, but you should be willing to talk about your feelings to a certain extent. If she's flirting with you, flirt back. Gently tease her. Mirror her body language the best you can to make her comfortable. She's never going to make a move if she doesn't think you want her to. Ultimately, there's nothing that you can do that will force the girl to make the first move. You can only hope that she likes you and try to set up the right situation. If it seems like things are going well, relax and go with the flow. There will be a moment when it's clear she's going to make a move where she slides close to you or makes eye contact for a long time while smiling.

SUMMARY:
Make yourself available. Set up an "accidental" romantic situation. Drop hints. Be open. Encourage her. Let things happen.
