Article: Make sure the packaging tape overlaps the top and bottom halves of the plastic bottle so it can create an airtight seal. Guide the tape around the bottle and press it tightly against the plastic to seal it. Continue wrapping around the bottle 2–3 times with the packaging tape so it doesn’t come undone or break. You can also try using duct tape to help seal the bottle.

Article: Apples, celery, and carrots are crunchy, and eating them can help scrub surface stains off of your teeth. In addition, they may kill bacteria and improve your breath. These products (milk, cheese, yogurt, etc.) contain lactic acid, which might help protect your teeth. Some of them can also help whiten your teeth and/or prevent some stains:  Hard cheeses can scrub some surface stains from your teeth, and block some stain-causers such as wine or coffee from discoloring your teeth, if you eat some prior to drinking. Eating dairy products is good for your teeth, but don't consume too much of sugary foods such as ice cream, as these can contribute to tooth decay. Sage has an antiseptic effect, and for this reason is even found in some mouthwashes and gargles. It can also help to whiten your teeth. Simply rub fresh sage leaves on your teeth. Strawberries contain an enzyme called malic acid that may help to whiten your teeth. You can simply rub a sliced strawberry on your teeth, or mash fresh strawberries into a paste and rub it on your teeth. Leave it on your teeth for five minutes, and then rinse with water. Brush and floss your teeth as normal afterwards.  You can add half a teaspoon of baking soda to the paste, if desired. Research shows that a strawberry paste will only remove surface debris. If you want more intensive whitening, seek other treatments. Natural bleaching agents found in lemon can help whiten your teeth; however, the citric acid found lemons can also wear away your tooth enamel, so you should not overuse this method. Simply take a slice of lemon peel and rub it on your teeth.
Question: What is a summary of what this article is about?
Eat crunchy fruits and vegetables. Eat more dairy products. Use sage to scrub your teeth. Make a strawberry paste. Use fresh lemon.
Article: Use a spice grinder to grind the toasted sesame seeds into a fine powder. There should be no solid seeds left when done. If you do not have a spice grinder, consider using a coffee grinder or mortal and pestle, instead. In a small bowl, whisk together the ground sesame seeds, dashi, soy sauce, sugar, sake, rice vinegar, and black pepper until the mixture is evenly blended.  For this sauce, you could pulse the ingredients together using a blender instead of whisking by hand, if desired. Doing so can help combine the solid ingredients—the ground sesame seeds, the sugar, and the black pepper—more thoroughly. Note that this is the other common sauce served with shabu shabu, and it, too, can be purchased commercially to save time. This sauce will end up being light brown. Transfer the sauce to a second shallow serving dish.  The bowl needs to be shallow so that you can dip food into the sauce without difficulty. Do not combine the sesame sauce and ponzu sauce. The two must be kept in separate dishes. The sauce can be served without any garnishes, but garnishes can add color and an extra splash of taste. Thinly sliced green onions, a small sprinkle of chopped garlic, and a dash of ground red pepper are good choices for sesame sauce.  Add the garnishes to taste. Keep in mind that they should accent the sauce, not overwhelm it or mask it. Set the sesame sauce aside until you are ready to serve the shabu shabu.
