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.

Problem: Article: She will be able to help you formulate a diet specifically for you. Keep in mind that your body and your symptoms will respond differently to foods than others who also suffer from Crohn’s disease. Part of finding the right diet will be trial and error at the beginning, but your doctor or dietitian can help you make a plan to begin. Try eating five to six small meals per day rather than three large ones. Some areas of the inner surface of the small intestine are damaged due to inflammatory processes. As a result, the effective length of the intestine is reduced (effective length means the functional part of the intestine that can handle food effectively for digestion and absorption). Thus, the diseased intestine cannot handle the same volume of food as a normal intestine can. If you eat a large meal, a significant portion will remain undigested and will pass into the colon. This portion will be fermented by colonic bacteria causing bowel gas, flatulence, bloating etc. This will also cause you to retain water in the intestine, causing diarrhea. Most Crohn’s disease patients experience repeated bouts of diarrhea, making them prone to dehydration. From this, many patients develop kidney stones due to concentrated urine. Dehydration also makes you weak and lethargic. A simple way to assess whether you have dehydration is the feeling of thirst. Drink at least 2–3 liters (0.5–0.8 US gal) of water daily to prevent dehydration. Sports drinks that provide electrolytes can also help replenish your system after a bout of diarrhea.
Summary: Visit a doctor or dietitian. Eat smaller meals at more frequent intervals. Drink adequate amount of water.

If you have not already done so, peel and slice 2 to 3 bananas, and put them into a plastic bag. Leave them in the freezer overnight so that they are nice and firm. The more milk you add, the creamier the ice cream will be. You can use almond milk or coconut milk—or any other non-dairy milk. If you are making mint chocolate chip ice cream, use only 2 bananas. All other flavors will require 3. Bananas are sweet on their own, but not everyone likes their taste. You can change the flavor to a certain extent by adding some additional ingredients. Here are some ideas to get you started:  To make chocolate ice cream, add ¼ teaspoon of vanilla extract and 3 tablespoons of cocoa powder. To make mint chocolate chip ice cream, add ⅛ teaspoon of peppermint extract. You can also add a drop or two of green gel food coloring. To make strawberry ice cream, add 1 cup (200 grams) of sliced, frozen strawberries and ⅛ teaspoon of vanilla extract. To make vanilla ice cream, add ½ teaspoon of vanilla bean paste or ½ teaspoon of vanilla extract. From time to time, you may have to pause the blender/food processor, and push any lumps or clumps down towards the bottom with a rubber spatula. Keep blending until everything is evenly mixed together. At this point, your ice cream is done. You can step it up by adding in some extras, however. Toss in some chopped nuts, chocolate chips, or sprinkles, and gently fold them in with a rubber spatula.  If you are making mint chocolate chip ice cream, you might want to stir in a handful of chocolate chips (dark chocolate or vegan). If you are making strawberry ice cream, you might want to stir in a handful of diced, frozen strawberries. At this point, the ice cream is ready as a soft-serve style. If you want it to be more firm, transfer it into a freezer-safe container, and leave it in your freezer for 30 minutes.

One-sentence summary --
Peel, slice, and freeze the bananas ahead of time. Add all of the ingredients into a blender or food processor. Add some flavor. Blend until everything is smooth. Stir in some extras for texture. Serve the ice cream, or freeze it for another 30 minutes.
