In one sentence, describe what the following article is about: Dietary changes remain a controversial method of influencing a baby's sex. Many doctors and scientists doubt that diet can exert any strong influence on a child's sex and consider the sex of a baby to be based on random chance.  Nevertheless, if your doctor says that it is safe for you to adjust your diet to promote having a girl baby, there is little harm in trying a "girl diet." Dietary changes can supposedly affect your likelihood of conceiving a girl by altering the mineral content and acidity of the uterine environment. According to this theory, a woman's diet in the weeks leading to conception can make her body more "friendly" toward X chromosome sperm (which lead to a baby girl) and less "friendly" toward Y chromosome sperm (which lead to a baby boy). Recommended foods on a diet conducive to having a girl include low-sodium dairy products, eggs, rice, and low-sodium breads and crackers. Fruits and vegetables might also help you conceive a girl. A 2008 study found that women who ate potassium-rich cereals were more likely to conceive boys.  Other potassium-rich foods include bananas, salmon, mushrooms, beans, tuna, sweet potatoes, and potatoes.
Summary: Talk to your doctor about making dietary changes. Change your diet to change your body chemistry. Eat a diet high in calcium and magnesium. Avoid potassium and sodium-rich foods.

In one sentence, describe what the following article is about: To make this type of volcano, you will need a two-liter bottle of cola, a roll of Mentos brand candy mints, and a large open area. Diet cola appears to work better than regular soda (it’s also less sticky than regular soda). Sodas with caramel color look more like ‘lava’ when they erupt as compared to clear lemon-lime sodas. This experiment is best done outside, but if you must be inside, lay down a large plastic tarp first. Avoid doing this experiment inside, as it will create a huge, sticky mess. Make sure your outdoor area is also uncovered since the soda can erupt quite high. Remove the cap from the soda bottle. Warn any spectators to stand back. When Mentos come in contact with the soda, a reaction occurs that causes the carbon dioxide gas in the soda to push the liquid out of the bottle. The more Mentos you drop in all at once, the greater the eruption; however, this can be difficult. There are a few different ways to deliver the Mentos into the bottle.  Method 1: Make a paper tube with the same width as the bottle neck. It should be long enough to fit the number of Mentos you want to put inside. Place an index card over the bottle mouth, place the tube over the hole, and fill it with Mentos. When you are ready to erupt, you will slide the card out, releasing the Mentos into the bottle.  Method 2: Loosely scotch tape the entire roll of Mentos together. When it’s time, you will drop the taped chain directly into the open bottle. Method 3: Insert into the bottle a funnel with a mouth that is wide enough to allow the Mentos to pass, but small enough to fit inside the neck of the bottle. You will drop the Mentos through the funnel and remove the funnel once the Mentos are in the bottle. Getting all the Mentos to fall in the bottle simultaneously is quite hard. If done incorrectly, the volcano will only rise a few inches or so. Practice getting the Mentos to drop simultaneously a few times before wasting your bottle of soda. Once the Mentos drop into the bottle, run a few feet away to observe the eruption!  If using the paper tube method, remove the card holding the Mentos in place and let them all slide into the bottle at one time. If using the tape method, simply drop the piece of taped-together Mentos into the mouth of the bottle. If using the funnel, drop all the Mentos into the funnel at the same time. Remove the funnel once they’re all in and run back.
Summary: Gather the necessary materials. Position the volcano in a large, outdoor area and open the soda bottle. Prepare a whole roll of Mentos to drop into the bottle. Release the Mentos into the bottle and run.

In one sentence, describe what the following article is about: Gardening urns most often come in sizes that range between 12–29 inches (30–74 cm) wide and 12–24 inches (30–61 cm) tall. For this reason, they're best suited for planting showy annuals and perennials that don't put down deep roots. Many popular container species like azaleas, impatiens, and hostas also tend to do well in urns.  Dahlia, geraniums, impatiens, and other showy annuals are good for filling urns with bright bursts of color, while hearty perennials like blue star juniper or Creeping Jenny may be a better choice for gardeners with less time to devote to upkeep.  No matter what you choose to display in your urn, the most important thing is that the planter be about twice the size of the root system once it reaches maturity. Talk to someone at your local greenhouse or plant nursery or look up information online to find out how big you can expect a particular species to get. Oversized urns are typically spacious enough to house a variety of plants, making your companion-planting options nearly limitless. Try pairing 2-3 different offerings to put together your own unique arrangements. In addition to creating a more eye-catching display, combining multiple plants in the same container will help you save precious space in your garden and in smaller containers.  A cluster of peach-colored tulips, for example, will stand out in dazzling contrast to a bed of white heliotrope.  For best results, stick with plants that have similar soil, water, and sunlight needs, as they’ll all be sharing the same resources. If you have a little extra space to play around with after incorporating your main show plants, consider filling it out with some lush greenery. Grasses like fountain grass, fescue, and bluestem lend decorative urns a textural depth that can be used to balance out the bold colors of annual flowering plants.  Plant tall, spiky grasses in the center of the urn to serve as an impressive focal point, and sew cascading species around the perimeter of the planter for a more elegant overflowing effect. Most species of grasses are relatively low-maintenance, but they can compete for resources with your main display pieces, so make sure your arrangements get plenty of water and sunlight throughout the day.
Summary:
Stick to small or medium-sized flowering plants. Mix-and-match plants in large urns. Fill out your planter with ornamental grasses.
