Probably should be 6: red, orange, yellow, green, blue, and brown. However, there are actually 21 different colours.
The 21 colours: black, blue, light blue, brown, cream, gold, gray, green, aqua green, teal green, dark green, maroon, orange, pink, dark pink, purple, light purple, red, white and yellow.
Around certain holidays, you many see M&M bags with different colors or color combinations. At Christmas time you may find M&M bags with red and green M&M's only. During Easter, you may find bags with pastel-colored M&M's.
M&M's are the nation's top-selling candy and the only sweets offered on Air Force one. In 1995, after an election that drew 10 million votes, the company added blue and dropped the tan colour, prompting a blacklash. Some people alleged that the M&M's were originally developed so that soldiers could eat candy without getting their fingers sticky. Many Amerians still refuse to eat the red M&M's because of the Red No.2 scare in 1976.
What is Zulu time?
The world is divided into 24 time zones. To make communication easier, each time zone has been given a letter of the alphabet ( the letter "I" and "O" are not used ).
For military, maritime, and other activities thtat cross time zones, the international reference of time is the clock at Greenwich, England. the letter designation for this clock is "Z". In the phonetic alphabet, Zulu is used for the letter Z. Thus, the Greenwich, England, time is known as "Zulu time".
Times are usually written in a 24-hour (military) format followed by the letter designating the time zone. For instance, 1830Z would be 6:30 pm in Zulu time.
Zulu time is formally known as Greenwich Mean Time (GMT). The offcial name today is Coordinated Universal Time (CUT). Actually, GMT, CUT, and Zulu time all refer to the same thing.
What makes us yawn?
Don't think we yawn because we're bored, most authorities agree that yawning is simply a way for the body to compensate for less oxygen in the bloodstream.
Every cell in our body needs a continual supply of oxygen. When we breathe normally, we take air into our lungs, which pass the oxygen to the blood so that oxygen can be carried throughout our body. When we exhale, we get rid of the waste product, carbon dioxide. If we're tired, we tend to breathe more slowly than normal and our body doesn't get all the oxygen it needs. Because we also are not getting rid of the carbon dioxide, it builds up in the blood. Our brain sense this and quickly sends a signal to the lungs to take an extra deep breath. This extra deep breath is call a YAWN.
What makes the sound when you snap your fingers?
When you rub two fingers together, the loudest sound occurs when the air is forced out between the middle finger and the palm and the air strikes the palm. You can test this theory by first snapping your fingers and listening to the sound. Next, place a soft tissue or piece of clth on your palm and try snapping your fingers. The sound will be very muffled.
Does hot water freeze faster than cold water?
When water is boiled until all the trapped air bubbles are released, it will freeze faster than cold water. But hot water doesn't freeze faster because it's hot but because it has a different compostion from the cold water that still has the trapped air bubbles.
When you heat water you promote evaporation that causes two cooling effects. First, some of the mass is carried off so there is actually less water to be cooled. Second, during evaporation the hottest molecules are released into the air first, thus lowering the temperature of the remaining water. This is why you can cool your soup by blowing on it. When you blow on the soup, it removes the water capor hovering above it and helps evaporation.
Why are the ocean salty but not lakes?
Most of the salt in the oceans comes from rockes containing various salts. Wind, rain, and erosion gradually wear down mountains and rocks. Rain then dissolves the salts into strams that eventually reach the sea. This has been going on for millions of years and that's why the oceans are salty.
Although water vapor evaporates, rises from the ocean, and is carried to the land, the heavier salt is left behind. As the river waters from new rainstorms feed the oceans, they carry more salt. Thus, after every rainstorm the oceans become just a little bit saltier.
Most lakes are relatively new compared to the age of the earth, and the salt from rainwater has not had time to build up. In addition, many lakes have outlet streams or rivers to let the water out when it reaches a certain height. The lakes may also be in a cooler climate, which prevents a high degree of evaporation.
What is the difference between billiards, snooker, pool?
Carom, or French billliards, is played on a table without pockets and only three balls are used, two white and one red. One white ball is the "cue" ball, and the remaining balls are "object" balls. To score a point, called a "carom" or "billiard," a player must hit the cue ball so that it then hits the other two balls in succession. In some games, the cue ball must also hit a cushion one or more times to complete a carom. Carom is now a generic term for any game played on a table without pockets.
Snooker is played on a table that has six pockets. The game is played with a cue ball and 21 other balls; 15 are red and 6 are numbered, colored balls. A player must first shoot a red ball into a pocket. The player then tries shooting any other colored ball into a pocket. If successful, the player continues to alternately hit red and colored balls into a pocket. Every red ball remains in the pocket but each colored ball is removed and set on the table again. Once all of the red balls are in the pockets, the six coloured balls must be shot into pockets in their numberical order.
Pool, which is also called "pocket, billiards," is also played on a six-pocket table. However, the pockets are usually wider than those on a snooker table. The game is played with a cue ball and numbered balls. Solid colors are used for balls 1 through 8, and stripes for galls 9 through 15. There are many varieties of pool games. When "Chicago" is played, for example, all balls must be sunk in rotation. In "straight pool" balls can be sunk in any order. However, the player must indicate the ball and the pocket, and gets one point only if successful.
