Being a clown isn't all fun and games. Rodeo clowns expose themselves to great danger every time they perform. When cowboys dismount or bulls buck them off, rodeo clowns jump in front of the bulls and motion wildly to get their attention. In this way, rodeo clowns provide an alternate target and, in doing so, protect the rider. Of course, this is a very dangerous thing to do. So you see, sometimes clowning around can be serious business., Rodeo clowns entertain audiences by performing funny actions., Rodeo clowns perform a dangerous but important job by distracting bulls to protect riders., Cowboys often fall from bulls during rodeo competitions., Bulls are dangerous animals that should be avoided., Wolverines are medium-sized mammals. They weigh no more than 50 lbs. Yet they have earned their reputation for ferocity by killing prey many times their size. But why do they get in so many fights? The reason wolverines have so many conflicts with other animals, including wolves, cougars, and even bears, is probably because of the wolverine's preferred hunting style. Rather than chasing down or tricking its prey like most hunters, the wolverine prefers to take its meals directly from other hunters. So while a polar bear or a lone wolf might be enjoying a hard-earned carcass, a hungry wolverine may try to take its lunch. As you might imagine, this style of hunting gets the wolverine into plenty of fights., Wolverines frequently fight larger animals because they often try to steal their food., Wolverines are small animals that usually hunt alone., Wolves and bears are stronger hunters than wolverines., Wolverines weigh less than most large predators., Sometime in December of 1891, Dr. James Naismith was teaching gym at the YMCA College in Springfield, Massachusetts. It was raining, and Dr. Naismith was trying to keep his students active. He wanted them playing a vigorous game that would keep them moving. He rejected a few ideas that were too rough. Then Naismith had his breakthrough. He wrote out the rules for a game with peach baskets fixed to ten-foot elevated tracks. Naismith's students played against one another, passing the ball around and shooting it into the peach baskets. Dribbling wasn't a part of the original game. Also, it took a while to realize that the game would run more smoothly if the bottoms of the baskets were removed. This game grew to be one of the most popular sports in America today., Basketball players originally were not allowed to dribble the ball., Dr. James Naismith preferred indoor sports to outdoor sports., Basketball developed from a game Naismith created to keep his students active indoors., Peach baskets were difficult to use during early basketball games., What's that humming sound? Could it be the hummingbird, the only bird capable of backward flight? Hummingbirds have many unique flight habits that distinguish them from other birds. Most birds flap their wings up and down to fly, but the hummingbird moves its wings forward and backward very rapidly in a figure-eight pattern. This allows the hummingbird to hover in position. They can also fly upside down and move about very rapidly. Other birds have to push off with their feet to begin flying and work their way up to their top speeds. The hummingbird can both start flying at maximum speed and stop flying instantaneously. Once you've seen a hummingbird in flight, it's unlikely that you'll mistake it for another bird., Hummingbirds are able to fly faster than every other type of bird., Hummingbirds have unique flying abilities that distinguish them from other birds., Most birds must use their feet before they can begin flying., A hummingbird's wings move in a figure-eight pattern., Remember, if something is worth doing, it is worth doing correctly. That said, the key to making perfect cookies is merely a matter of preparation and precision. To begin with, read your cookie recipe thoroughly before baking. Make sure that you have all the necessary ingredients before you continue. Next, use good tools and utensils. Sometimes, the craftsperson is only as good as his or her tools. By using good tools, you minimize mistakes and improve the quality of your product. Last, use top-quality ingredients. If you use poor-quality materials, you'll create inferior products. So, to make perfect cookies, you should use the highest-quality materials available., Expensive ingredients are necessary for every type of cookie., Reading a recipe is the most important part of baking., Making high-quality cookies requires careful preparation, good tools, and quality ingredients., Bakers often make mistakes because they use the wrong tools., You might think that all automobile fuels are the same, but they aren't. Automobiles can run on one of three types of fuel: gasoline, diesel, and biodiesel. All these fuels are burned inside the engine, which creates the heat and energy used to power the car. But there are important differences between these fuels. Gasoline and diesel are more common than biodiesel, but each burns differently. Diesel fuel is heavier and less flammable than gasoline, so it has to be compressed before it will burn. Gasoline may be lighter than diesel, but both fuels are made from crude oil. On the other hand, biodiesel fuel is made from vegetables. Both biodiesel and diesel fuels must be burned in diesel engines. If gasoline is pumped into a diesel engine, it will have to be pumped out. These fuels may look pretty similar at the gas station, but there are important differences between them., Gasoline is the most commonly used automobile fuel., Biodiesel is better for automobiles because it is made from vegetables., Gasoline, diesel, and biodiesel all power vehicles, but they have important differences., Diesel fuel is heavier and less flammable than gasoline.
