Article: For the purposes of this example, we're using Diet Coke, but you can actually use any type of diet soda (as long as it contains aspartame). Warm soda causes better explosions, so avoid using cold/refrigerated soda. For best results, purchase room-temperature soda and then let it sit outside in the sun or in a pot full of hot (not boiling) water for a few hours before using it. Experiments have shown that while the original Mint Mentos will give you a longer explosion, Mentos Fruit will give you slightly shorter but more intense explosion. Other experiments have shown that Mint Mentos are the better choice because the gum arabic found in the mint coating reduces surface tension and quickens the carbon dioxide's escape from the bottle, making for a more intense explosion. As the rocket is more of a fast-acting affair, you might want to go for Mint Mentos. If you have the time and money to do so, why not try one bottle with Mint Mentos and one with Fruit Mentos, and then compare the results? You probably have this one lying around your house already, but if you don't, you should be able to buy a roll just about anywhere (hardware stores are a safe bet). Wearing goggles will not only protect your eyes from the soda-Mentos concoction, but also from any other debris (for example, the lid) that might fly out from the bottle once it hits the ground and explodes. Your rocket is likely to bounce around like crazy; make sure it has enough room to do that. If you're in a parking lot, make sure there are no cars nearby for at least a 50-foot radius, if not more. If there's a field or empty lot nearby, go there to make your rocket. You don't want to risk doing damage to anyone's car or home, as it could cost you or your parents a lot of money to repair. It's possible you'll get covered in the sticky Diet Coke-Mentos solution. Wear clothes and shoes that you don't mind getting wet and sticky preferably ones that are easy to wash.
Question: What is a summary of what this article is about?
Buy 1 2-liter bottle of Diet Coke. Buy 1 package of Mentos. Obtain one roll of masking tape. Buy protective goggles. Find a wide-open space to build the rocket in. Wear appropriate attire.

Problem: Article: The collar is padded to help your horse pull heavy carts like passenger carriages. Gently put the collar over the top of the horse's head. The collar should sit at the base of the horse's neck where it meets their body. You can put the collar on upside down if your horse has a large head or sensitive ears. After the collar is around the horse, twist it around to the correct position. The collar should fit snug across the horse's shoulder blades. The horse pulls the cart by pushing its shoulder blades into the collar. The breast strap is a wide leather band that fits around the horse's chest. It is a good idea for this to be padded if possible. Bring the breast strap in front of and around the horse's chest. To hold the breast strap in place, attach the martingale to the girth and the neck strap over the horse's withers. Most drivers connect the center of the neckstrap (over withers) to the top of the belly band of the harness. Fasten the buckle so the neckpiece sits securely and comfortably in the center of the horse's chest. The martingale is a strap on the breast strap that helps control the horse's head. The horse pulls the cart by pushing their chest into the breast strap. If the breast strap sits too high, it can push into the horse's windpipe and cause breathing troubles. If the breast strap sits too low, it may get in the way of the horse's leg movements. With most light harnesses, the traces are made onto the breast strap itself. If not, on the collar or breast strap, there is a leather strap and buckle used to attach the traces. Insert 1 end of the traces and fasten it with the buckle, then attach the traces to the other side. The traces are what the horse pulls the cart with. They should be run through the bellyband tie-downs and back toward the cart. They can be wrapped around the shafts or most often run through leather shaft guides then fastened to the cart itself at special hooks. Put the saddle on your horse so sits just behind the withers (base of the neck above the shoulders). Secure the saddle strap around the horse behind its front legs. Place the end with the breeching around the back end of your horse. Then, gently pull the horse's tail above the breeching. The saddle is made from leather straps and doesn't look like a riding saddle. The saddle and breeching also have small leather straps that sit across the horse's back called ornaments. You can simply slide them apart across the saddle area. Attached to the saddle are leather loops called tugs, which hold the shafts of your cart in place. The breeching works as the brakes of the cart or carriage. The crupper is a padded leather loop that goes around the horse's tail to keep the saddle in place. Loop the crupper around the horse's tail, and fasten the buckle to secure it in place. Your crupper should not be too tight that it raises up the horse's tail or pulls back on the saddle.
Summary: Use a collar if your horse is pulling a heavy carriage. Use a breast strap if you are driving a lighter cart. Buckle the traces to the collar or breast strap on both sides of the horse. Place the saddle and breeching around the horse's body. Fasten the crupper around the horse's tail.

It is important to know how to turn off speakerphone during a call without hanging up on the caller on the other end. Pick up the handset. By picking up the handset, your corded landline phone will automatically switch the call from the built in speaker to the handset earpiece. Push the speakerphone button. If your landline phone has a headset attached, simply depress the "'Speakerphone'" button on the phone and the call will automatically switch from the speaker to the headset. With a cordless phone it is not nearly as intuitive to turn off the speakerphone during a call. Press the talk button. On a cordless landline phone, such as the Panasonic KX-TGE233B, push the "'Talk'" button on the handset and the audio will automatically be switched from the speaker to the earpiece on the handset.
