Fun Facts about Science
The Sun gives off a stream of electrically-charged particles called the solar wind. Every second, the Sun pumps more than a million tons of material into the solar wind. The metal with the highest melting point is tungsten, at 6,170 degrees Fahrenheit. There are more atoms in a bucketful of water than there are bucketfuls of water in the Atlantic Ocean. The speed of light, at 670 million mph, sounds very fast. But a light ray, at this speed, would take about 26 billion years to cross the visible universe. Every day nearly 3,000 earthquakes shake Earth. There are more bacteria in and/or on the human body than cells making up the human body 20 millions sperm per ml is the threshold for clinical infertility; (50 million sperm per ml is normal). The amount of sunlight reaching the earth's surface is 6,000 times the amount of energy used by all human beings worldwide. The total amount of fossil fuel used by humans since the start of civilization is equivalent to less than 30 days of sunshine. Rubber products melted in hot weather, froze and cracked in cold, and adhered to virtually everything until the day in the mid-19th century when inventor Charles Goodyear accidentally dropped some rubber mixed with sulfur on a hot stove. Goodyear's discovery of what came to be known as vulcanization strengthened rubber so it could be applied to a vast variety of industrial uses, including, eventually, automobile tires. The Earth spins at 1,000 mph but it travels through space at an incredible 67,000 mph. In October 1999 an Iceberg the size of London broke free from the Antarctic ice shelf If you could drive your car straight up you would arrive in space in just over an hour. In 5 billion years the Sun will run out of fuel and turn into a Red Giant.
