00:00Hey, it's quiz time! Ready to strain your brain with these mind-bending true or false trivia questions?
00:05Let's get to it then!
00:07Spider silk was once used to make guitar strings.
00:15This is false. Spider silk was never used to make guitar strings, but it has been used to make violin strings.
00:23This is because spider silk can produce unique and thrilling sounds,
00:27making them a useful resource for building musical instruments.
00:31Astronauts crave spicy food in space.
00:39True! In space, most astronauts will lose their sense of smell,
00:43and our sense of smell is usually what makes us perceive the taste of food.
00:47Because of that, many astronauts begin to crave fiery sauces, such as Tabasco sauce,
00:53to make up for the lack of flavor in their food.
00:56Astronauts see the sun as yellow while they are in space.
01:05This is false. While in space, astronauts see the sun as white instead of yellow.
01:10As Earthlings, we perceive the sun as yellow due to a distortion caused by the Earth's atmosphere.
01:16But since there's no atmosphere in space, the sun appears like a huge white glowing sphere.
01:26A coconut is a nut.
01:34False! A coconut is actually a one-seeded drupe, i.e. a fruit with a hard covering and closing as a seed.
01:41In case you're wondering, peaches and olives are also drupes.
01:48Some lizards have green blood.
01:56This is actually true! The green-blooded skink, a lizard living in the country of Papua New Guinea,
02:02has high levels of a greenish pigment called faliverdin, which gives its blood a green color.
02:15You bet it's true! Sound travels about 17 times faster through steel than through air.
02:21This happens because molecules in a solid material are packed closer together than they are in a liquid or gas,
02:28which allows sound waves to pass more easily through them.
02:32In England, black cats are considered bad luck.
02:40False! Although black cats are considered symbols of bad luck in many places,
02:45they're actually considered good luck in England.
02:49NASCAR race car drivers can lose up to 20 pounds of sweat in a single race.
02:58This is false!
03:01Still, NASCAR race drivers can lose up to 10 pounds of sweat in just one race.
03:06This happens due to a variety of things including the high temperatures outside, heavy uniforms, and accumulated heat inside the cars.
03:15Odontophobia is the fear of teeth.
03:22Yes, it is! People with odontophobia, also known as dentophobia or dental fear, do not enjoy going to the dentist.
03:32A referee at a FIFA World Cup soccer tournament runs about 30 miles during an average game.
03:39False! Referees sure run a lot, but they run an average of 12 miles per game.
03:45The world's largest desert, the Sahara in Africa, is about the size of the Amazon rainforest in Latin America.
03:55False! The Sahara is enormous, but its 3.3 million square miles are about the size of Australia, not the Amazon.
04:04Geckos usually eat their skin as soon as they shed it.
04:12True! Geckos love to munch on their skin, but they can't live on that alone, of course. They also eat bugs. Yum!
04:20Ostriches are one of the few species of bird that cannot fly.
04:30This is absolutely true!
04:32Ostriches have wings, but they can't fly. However, ostriches are fleet, strong runners.
04:38They can sprint up to 43 miles an hour and run over 31 miles an hour.
04:43They may use their wings as rudders to help them change direction while running.
04:48The first macaroni and cheese recipe ever to be registered was back in the 13th century.
04:54True! It's hard to believe, but macaroni and cheese is believed to be a traditional dish.
05:00Foodie historians found an Italian cookbook from the 13th century with what they believe to be an early mac and cheese recipe.
05:08The black box in a plane is black.
05:13Hmm. As confusing as this may sound, this is false.
05:17Airplane boxes are actually orange. The so-called black boxes document everything that happens on board a plane.
05:24In case of an accident, they need to be a bright color in order to make them easier to find.
05:29Haven't you heard? Orange is the new black.
05:33M&M stands for Mars and Murray.
05:37Yep. This is true. These are the last names of the candies co-creators.
05:43A is the most common letter used in the English language.
05:48Yup, this is true.
05:52These are the last names of the candy's co-creators.
05:56A is the most common letter used in the English language.
06:02False.
06:06The most common letter used in English is E. It appears in about 11% of all English
06:11words according to the Oxford Dictionaries.
06:14A lion's roar can be heard up to 5 miles away.
06:22This is true.
06:27Monaco is the smallest country in the world.
06:31Nope, false.
06:34The smallest country in the world is Vatican City in Rome, with a total of 17 square kilometers.
06:42Madonna's real name is Madonna.
06:47True.
06:50Madonna was born Madonna Louise Saccone.
06:55Coffee is made from berries.
07:02This is true.
07:03The liquid coffee we drink goes through a long process.
07:07Originally, farmers picked out coffee berries, then they are processed and dried.
07:12The beans are then roasted and ground and finally ready to be consumed.
07:17An octopus has three hearts.
07:20True.
07:23An octopus has one main, systemic heart to pump blood around its body.
07:27The two additional hearts are responsible for pumping blood over each of its gills.
07:32Venus is the hottest planet in the solar system.
07:37True.
07:40Although Mercury is closer to the Sun, it has no atmosphere so it is subject to great
07:44temperature fluctuations.
07:47But Venus has an average surface temperature of around 850 degrees Fahrenheit, making it
07:52the hottest planet in our system.
07:56Bananas are curved because they grow upwards toward the Sun.
08:02True.
08:03A process called negative geotropism means the fruit grows upwards to break through the
08:08canopy.
08:10Fish can blink.
08:15This is false.
08:16It would be pretty cute if they could though.
08:19Hot and cold water sound the same when poured.
08:25False.
08:26Weird fact, but they sound different due to the fact that hot water has a higher viscosity
08:31than cold water.
08:34Denmark has twice as many pigs as they have people living there.
08:39True.
08:41Denmark has a human population of more than 5 million, but its pig population is twice
08:46as big as that.
08:49No one has ever traveled around the world in a hot air balloon.
08:54This is false.
08:56In March 1999, Brian Jones and Bertrand Piccard made the first non-stop flight around the
09:02world in a balloon.
09:04Their journey began in Switzerland and finished over Africa.
09:07It took them just 20 days.
09:10Scientists developed a fork that measures how fast you eat your food.
09:15Yup, it's pretty true.
09:19The inventors hope that people will use this fork in order to learn to eat more slowly.
09:25The acronym NASA stands for the National Astronomy and Space Administration.
09:31False.
09:35NASA stands for National Aeronautics and Space Administration.
09:41Astronauts grow about 6 inches in space.
09:44False.
09:456 inches is a lot.
09:48Usually, astronauts can grow between 1 and 2 inches when they're traveling through space.
09:52This happens due to the lack of gravity, which makes the human spine stretch out, causing
09:57astronauts to grow a little bit.
10:00There is a scientific reason why people fringe when they listen to nails scraping a chalkboard.
10:06True.
10:09Fingernails scraping a chalkboard produce a similar sound frequency to those of a chimpanzee's
10:13warning call.
10:14So the sense of distress humans might feel when fingernails scrape could be a sign that
10:18our fundamental primate danger sensors have been triggered.
10:22Medieval bakers used to color their flour white with the help of chalk.
10:30This is true.
10:31Back in the day, white bread was a sign of wealth and was sold at higher prices.
10:36So some bakers used to color their flours with chalk in order to sell whiter bread.
10:45That's it for today!
