Article: Coca-Cola is probably the most famous brand in the world, and in some areasyou can even access it easier than clean drinkable water. Although the company is trying to present itself as a health-conscious company, you can't really say that drinking cola is healthy for you. Still, we all drink cola, some more and some less, and we tell ourselves that it's all okay as long as we don't overdo it. However, Coca-Cola has other functions besides drinking. Cola removes the tarnish from old pennies. Got some old rusty pennies? Not to worry! Put them inside a glass of cola and let them rest for a while. When you get them out, you'll have shiny pennies that will look as if they were coined a couple of days ago. If you couldn't clean those pennies with industrial acids, just buy a can of cola and let it do its magic! You can remove gum from your hair with cola. If you've got gum stuck in your hair and don't know a better way to get it out, don't worry, you won't have to cut it. Just pour some cola into a bowl and dip the part of your hair with gum on it inside. Leave it for a couple of minutes and then simply wipe off the gum. You can make an exploding fountain. You probably know about this one. You can make an exploding fountain by putting a mint inside a two-liter bottle. Then move away from the bottle and get ready for a Coca-Cola explosion. This is a fun thing to do, but it is also a warning -- don't eat a mint and drink cola at the same time, because a similar thing could happen to your stomach.
Answer: Take the place of acids.
answer:
What can cola be used to do?

Article: " Dining out", or " eating out ",is a phrase people use in Britain when they eat in a restaurant or a pub. Eating out is more popular in Britain today than ever before. However, eating out can be expensive. Restaurants are normally more expensive than pubs, though many pubs serve very good ,simple food. As British people don't dine out every night of the week ,eating in a restaurant is often seen as a special occasion. When going for the first date, or if celebrating an anniversary or a birthday, many people like to go to a restaurant. People often eat in a restaurant before going to the cinema or the theatre. As in all cultures, there are many rules of etiquette surrounding food and eating, and nowhere is this more _ than when eating in a smart restaurant. People are almost always expected to eat with a knife and fork and these should be held in the correct hand and used in the correct way. It is also impolite to have your elbows on the dining table when you are eating. There're many such "unspoken" rules -- they are normally only important when eating in a very elegant and expensive restaurant, and vary slightly from restaurant to restaurant and place to place. A recent nationwide survey showed that there was a divide in manners between the north and south of Britain ---the "worst" manners were in Scotland and the northeast, and the "best" in Wales and the southeast! However, this survey was almost certainly conducted by someone in the southeast, so it may not be entirely fair. Naturally, restaurants vary greatly in quality and price. However, almost all British cities have a vast range of food and cooking styles to choose from as well as traditional British food, from the very cheap to the very expensive -- French, Italian, Indian, Greek, Thai, Japanese and many more. In fact, when asked what their favorite food is, many British people say an Indian curry rather than any other dish! As well as dining in a restaurant ,when people are too tired to cook after work they often get a "takeaway". This means they order from a takeaway or takeout restaurant by phone, then go to collect it and take it home to eat. Many takeout restaurants also deliver to your house. While you can normally find a takeout restaurant for almost any cuisine, the most popular are Italian, Indian and Chinese -- and all you have to do is to open the door, pay and eat!
Answer: Traditional British food is seldom served in British restaurants.
