But have you ever thought about what happens on the plane?Here are some of the most interesting things that happen.Do planes drop human waste while in flight?When you flush（冲）a toilet on a plane at an altitude of 30,000 feet, there must be a question in your mind: “Is this about to land on a farmers house?”Take it easy. A planes toilets cannot be emptied in the sky. The waste is stored in tanks on board and can only be operated by the ground crew.However, why is news like “blue ice falling out of a plane” reported? Is blue ice human waste? Stories about blue ice are true but rarely happen. The FAA said some toilet holding tanks have a blue chemical in them. If a tank leaks high in the air, the water freezes once it hits the outside air, and melts before it lands on the ground.Is turbulence (颠簸) dangerous?Its scary, uncomfortable and spills your drink. But is turbulence something you really need to worry about?Absolutely not. Its part of flying, and it isnt dangerous. Turbulence is caused when two masses of air hit one another at different speeds. Wind, thunderstorms and closeness to mountains are all possible reasons. Despite how dangerous it feels, turbulence wont crash your plane. Even in extremely rough air, the wing is not going to break off.Why are plane windows round?If you have traveled by plane before, you may have noticed that every plane window has a round design. This isnt to make the plane look good. Its for the safety of everyone on board. As the airplane flies higher and higher, the outside atmospheric pressure gets lower and lower. In the end, the pressure inside the plane becomes greater than the pressure outside. At this time, windows that can resist pressure are needed.Square windows can crack. The different pressure inside and outside put stress on the right angles. However, rounded corners help to reduce these stresses by spreading them around the window.21.

Neither of us makes a lot of money, but years of experience have taught us how to walk between the raindrops and make it from one month to the next with a fair amount of grace. I cook a lot at home, more when were facing difficult times. When I know that I have to keep us fed on not much money, I fall back on my grandmothers recipes. She taught me to cook. When I was a kid, my twin brother and I spent long summer weeks and Christmas vacations with my mothers parents in the mountains of North Carolina. Rather than go hunting with my grandfather on mornings, I found myself more and more in the kitchen with my grandmother, watching her making a lemon cheese pie with her soft hands. My great-grandmother died when my grandmother was 11 years old. As the eldest daughter, she was expected to take on all of the housework while attending school. Throughout the Great Depression, she learned how to make a little food go a long way. Vegetables were cheap, so she cooked a lot of them, mostly only using small amounts of meat for seasoning. Roast beef was a twice-a-month luxury, but there was nothing she couldnt do with a chicken, every part of it. Nothing went to waste. Now I understand that her food was sacred (神圣的). I feel connected to my grandmother and to hundreds of years of family when Im in my kitchen making country food. In the delicious smells is a long tale of victory over hard times, of fighting starvation of not just surviving, but finding joy and pleasure in every meal of every day. From grandmother I learned to take real satisfaction in feeding people. My grandmother would beam with pleasure over a heavily laden table and say: “Do you know what this would cost at the re
