People have always had to find ways to keep food safe to eat. Methods to dry, smoke and salt food were invented thousands of years ago. The process of canning is much more recent. This storage method keeps food safe to eat for long periods of time. Today, canning is one of the most popular methods of storing food.
Canning uses heat to kill bacteria and other micro-organisms that cause poisons to form in food. Canning also takes away the air that these organisms need to live. One popular method of canning uses a water bath.
Clean fruits or vegetables are placed in glass bottles. The food can be put into the bottles either hot or cold. The cold method is used for soft fruits and vegetables that could lose their shape or taste. Firmer fruits and most vegetables are usually cooked. They take up less space in the bottles. After the food has been placed in glass bottles, boiling water is poured into the bottles to about three centimeters below the top. Then covers are placed on the bottles, but are not turned all the way. The bottles are placed in a large container filled with warm water that is then brought to a boil. The water must completely cover the bottles, from three to five centimeters over the top. When the water boils, any air in the bottles will be expelled. The boiling continues for several minutes. Then the bottles are allowed to cool. Finally, they are placed briefly into cold water. This makes a strong barrier to keep the air out. In other words, a vacuum is created. When the bottles are completely cool, notes can be placed on them to identify what is inside. The bottles can then be stored in a cool, dark place at a temperature of between four and twenty-one degrees Celsius.
Canning allows your family to enjoy foods that might not come fresh throughout the year. It is also a good way to store food for six months to a year, or even several years, in case of an emergency. It does not cost much to continue canning every year once the equipment has been purchased.
You can get more information about canning food from the group, Volunteers in Technical Assistance. VITA is on the Internet at vita.org.

56. Terminal examination is coming near and it is getting hotter and hotter. Michael studies hard at his desk, often wet through with sweat. Now what he is most longing for is some kind of instrument that can cool himself while he is doing his lessons at the desk so he can have a better learning result.

57. It is only a few days before Christmas Day. Jacky and his family are to give their house a thorough cleaning. As his father has some trouble with his health, Jacky volunteers to undertake the task of cleaning the ceiling and walls. In order to do a better job, he is eager to find an ideal instrument to match his aim.

58. For the purpose of being admitted by a key university, Harry has been burying himself in lessons and often studies until late into the night so that he often feels tired out and sleepy. “Why not refresh myself with a cup of coffee now and then?” He thinks and then he comes up with an idea….

59. Simon has decided to go hiking with his classmates for a holiday and hopes to have a picnic by cooking in the open air to add pleasure and fun to their trip. Now he is given the task that he should get an instrument with which they can cook delicious dishes.

60. Peter’s mother is a cleaner whose job is to get clean kinds of floors, including carpets of many buildings. The boring work — especially the stair carpet cleaning — often makes her mother worn out. So Rachel is anxious to buy her an easy-to-use machine to take the place of her mother’s heavy work.

An early invention by Albert Einstein has been rebuilt by scientists at Oxford University. They are trying to develop an environmentally friendly refrigerator that runs without electricity.

We all know that modern fridges cause damage to the environment. They work by using a kind of man-made greenhouse gas called Freon (氟里昂), which is far more damaging than carbon dioxide.

Now Malcolm McCulloch, an electrical engineer at Oxford, is leading a three-year project to develop appliances that can be used in places without electricity.

His team has completed a prototype (样机) of a fridge patented in 1930 by Einstein. It used only pressurized gases to keep things cold. The design was partly used in the first refrigerators, but the technology was dropped when more efficient compressors (压缩机) became popular in the 1950s. That meant a switch to using Freon.

Einstein’s idea uses butane (丁烷) and water and takes advantage of the fact that liquids boil at lower temperatures, when the air pressure around them is lower.

“If you go to the top of Mount Qomolangma, water boils at a much lower temperature than it does when you’re at sea level and that’s because the pressure is much lower up there,” said McCulloch.At one side is the evaporator (蒸发器), a bottle that contains liquid butane. “If you introduce a new vapor above the butane, the liquid boiling temperature decreases and, as it boils off, it takes energy from the surroundings to do so,” says McCulloch. “That’s what makes it cold.”

The gas fridges based on Einstein’s design were replaced by Freon-compressor fridges partly because Einstein’s design was not very efficient. But McCulloch thinks that by changing the design and replacing the types of gases used it will be possible to quadruple (翻两番) the efficiency.

However, McCulloch’s fridge is still in its early stages. “It’s very much a prototype,” he said. “Give us another month and we'll have it working.”
