⁉️ How fast is terminal velocity of a bullet?
✅ Hatcher calculated that his .30-caliber rifle bullets reached terminal velocity—the speed at which air resistance balances the accelerating force of gravity—at 300 feet per second. You might die from a bullet moving at that speed, but it's unlikely.

⁉️ How does salt help preserve meat?
✅ Salting, especially of meat, is an ancient preservation technique. The salt draws out moisture and creates an environment inhospitable to bacteria. If salted in cold weather (so that the meat does not spoil while the salt has time to take effect), salted meat can last for years.

⁉️ What is the color of the black box in a commercial airplane?
✅ Black box or flight data recorder, mounted in the tail of an aircraft, is one of the most important gadgets that is used to reconstruct the events leading to a plane crash. The term "Black Box", however, is a misnomer as its colour is orange. This is done for easier location after a crash.

⁉️ Can graphite conduct electricity?
✅ Graphite is an electric conductor, consequently, useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.

⁉️ Why do people throw rice at weddings?
✅ Throwing rice at a newly married couple has been a tradition for thousands of years, possibly going back as far as the ancient Assyrians and Egyptians. The idea is to give the newlyweds good luck, fertility, and abundance using this symbol of a good crop.

⁉️ Which country is known as the land of the midnight sun?
✅ Canada (Yukon, Northwest Territories, and Nunavut), Greenland, Iceland, Finland, Norway, Russia, Sweden, and the United States (Alaska). A quarter of Finland's territory lies north of the Arctic Circle and at the country's northernmost point the sun does not set at all for 60 days during summer.

⁉️ What connects the Pacific Ocean and the Atlantic Ocean?
✅ The Panama Canal is not the only water line connecting the Atlantic and Pacific Oceans. There's a place in Wyoming—deep in the Teton Wilderness Area of the Bridger-Teton National Forest—in which a creek splits in two. Like the canal, this creek connects the two oceans dividing North America in two parts.

⁉️ What color do dogs eyes reflect?
✅ The colors of a dog's eyeshine aren't limited to red and green, either. They can be all shades of blue, orange, yellow, turquoise or even violet. The specific color reflected depends on the amount of zinc or riboflavin in the eye cells. Red glowing eyes at night are the result of blood vessels reflecting light.

⁉️ Why are your lips red?
✅ Your lips' red or pink pigment comes from underlying blood vessels -- red-colored, blood-filled capillaries are close to the thin skin on your lips. The transition of the reddish-pink outline of your lips to the rest of the skin is called the vermillion border, and it's found only in humans .

⁉️ How high can you go without oxygen?
✅ We pass out when the pressure drops below 57 percent of atmospheric pressure — equivalent to that at an altitude of 15,000 feet (4,572 meters). Climbers can push higher because they gradually acclimate their bodies to the drop in oxygen, but no one survives long without an oxygen tank above 26,000 feet (7925 m).

⁉️ When were hieroglyphics created as a written language?
✅ Archaeological discoveries suggest that Egyptian hieroglyphs may be the oldest form of writing. The earliest evidence of an Egyptian hieroglyphic system is believed to be from about 3300 or 3200 BC, and the Egyptians used hieroglyphs for the next 3,500 years.

⁉️ Do women have an Adam's apple?
✅ The Adam's apple is actually caused by the bulging of a set of cartilage plates that are held together by tissues and muscle fibers, which protect the vocal cords. Women have these plates, too, but the bulge is more prominent in men for two reasons: Testosterone causes the larynx to grow rapidly during puberty,
