Article: This experiment will use the reflection of light on objects to show how light moves in a straight line. You need to conduct this experiment with someone else, as one person will hold the flashlight and one person will hold the mirror. You will need the following supplies: Two to three sheets of black paper. A flashlight. A small mirror. Small objects like buttons, bottle caps, or dimes. Lay the black paper down on the ground in a lowly lit room or, if possible, a dark room. Then, place two to three small objects in the center of the paper. The person with the flashlight will sit in front of the objects with her back to the objects.The other person will hold the small mirror so it is facing the objects. The person will then turn on the flashlight so it is shining away from the objects. The other person will use the small mirror to reflect the flashlight so it hits the objects. Move close to the light, at an angle, to catch the light so it hits the objects. You may need to position more than one mirror to create a light path that shines on the objects. Play around with reflecting the light on the mirrors until the light hits the objects. You can also move the objects around the room to create a more complicated light path, using the flashlight as the light source. This experiment shows that light travels in a straight line in the air. But it also bounces off of a reflective surface, like a mirror. The angle of the light as it bounces off the mirror will be the same as the angle of the light as it hits the mirror. The mirror reflects the light and changes its path from a straight line to an angled straight line.
Question: What is a summary of what this article is about?
Gather your materials. Place the objects on the black paper. Have one person hold the flashlight and one person hold the mirror. Turn on the flashlight.

INPUT ARTICLE: Article: Look for a place behind rocks or trees for privacy. Don't forget to bring your supplies, including toilet paper, plastic bags, and hand sanitizer. If you're wearing a skirt, raise it and wrap it securely under one arm, then lower your underwear. If you have enough time and privacy, it's better to remove pants and underwear completely, just in case of urine dribbles. Set your pants and underwear on a dry spot on the ground or a nearby bush. Don't put them too close to you or you may soil them. You might be used to squatting on the balls of your feet, with your feet close together, but this position is very unstable and hard on the knees. Squatting with feet hip-width or shoulder-width apart and with your feet flat is easier to hold for an extended period of time. If you're wearing pants, be careful not to let things fall out of your pocket as you squat. Push your urine stream hard at the beginning and at the end to get a strong stream and not dribble. Some women find it helpful to use one hand to spread the labia and better expose the urethral opening, but this can also be accomplished by spreading the legs a bit farther. If you prefer not to squat, you can try the steps in How to Urinate Standing up As a Female. Hopefully you've brought a plastic bag, so you can pack out your used wipes: take it with you when you leave, disposing of it when you get home or back to camp. If not, just drop your used wipe in your pee spot. If you need to change a tampon, be sure to pack the old one out in a plastic bag and dispose of it in the nearest facility. Tampons do not break down and the blood will attract animals. Alternately, you can bring down your skirt if you are wearing one, and make sure that it is not tucked into your underwear. Don't forget to use the hand sanitizer you've brought.

SUMMARY: Find a private spot. Lower your pants and underwear. Squat with your heels flat on the ground. Urinate. Wipe with toilet paper, tissues or a wet wipe. Pull up your underwear and pants.

Leaving dirt or other particles on the wood can keep it from properly absorbing the paint, primer, and sealant. Clean the wood before applying sealant by wiping it down with a damp cloth. You can use a tack cloth to pick up any remaining dirt. Tack cloths are gauze-like materials treated with a sticky substance and can be purchased at any home improvement store. Brush a thin coat of glossy acrylic medium sealant onto the wood using a dampened sponge or paintbrush. Allow the sealant to dry, and then apply another coat to the wood. Lightly sand the wood after the second coat of sealant has dried to remove any excess sealant and then wipe it down again with a wet cloth and tack cloth. Use a sponge for wood surfaces with grooves and curves and a paintbrush for flat surfaces. The sandpaper should be around a 220 grit. Using primer provides a surface to which paint can adhere by allowing the wooden surface to regain surface tooth (ridges and valleys). An acrylic gesso is probably your best option for using primers. You will only need to apply one coat of a high quality primer, lower quality ones might require a second coat. In order to maximize paint adhesion, you'll need to allow the primer time to dry. This could take several hours. Once the primer is dry to the touch, you can start applying your paint.
