Did you think Everest was the tallest mountain in the world? Or that giving kids sugar makes them hyper? Or that Albert Einstein was bad at math? Well, it turns out you were duped. We all were. Ripley's Believe It or Not!, the multimedia franchise devoted to all things weird, has produced this list of facts that refuse to be true no matter how many people believe them. It's a sobering reminder of how much we rely on received information. It's also good for laughing at people who believed more of these things than you did.

THE TOP 50 COMMON MISCONCEPTIONS RESOLVED

1. Coffee is made from beans.
While it is widely believed that coffee comes from 'coffee beans', experts say it is actually made from a seed which is called a bean.

2. Chameleons change color to match their surroundings.
Believe it or not, chameleons actually change color as a response to mood, temperature, communication and light instead of the object they are touching.

3. Mount Everest is the 'tallest' mountain in the world.
While Mount Everest is officially deemed the tallest mountain in the world, experts claim that technically it may not be. The summit of Everest is officially higher above sea level than the summit of any other mountain, but Mauna Kea is the tallest when measured from base to summit. However, the record books deem it the tallest because it has the highest peak on Earth.

4. The Great Wall of China can be seen from space.
The Apollo astronauts confirmed that you can't see the Great Wall of China from the Moon. In fact, all you can see from the Moon is the white and blue marble of Earth. Astronaut Chris Hadfield confirmed it's not visible from the International Space Station, either.

5. One human year is equivalent to seven dog years.
While true in some cases, it does not apply to everyone because it very much depends on the size and breed of the dog.

6. You lose your body heat fastest through your head.
While this is widely believed to be true, some experts say it is a myth and claim humans would lose the same amount of heat if they went without a hat as if they went without pants.

7. The Earth revolves around the Sun.
Technically, the Earth, sun and all of the other the planets are orbiting around the centre of mass of the solar system, not specifically the sun.

8. Different parts of your tongue detects different tastes.
This was scientifically disproven by research which found that all taste sensations come from all regions of the tongue, although different parts are more sensitive to certain tastes which may be where the popular saying comes from.

9. Peanuts are a type of nut.
Unbelievably, peanuts, along with beans and peas, actually belong to the single plant family, Leguminosae.

10. Giving children sugar makes them hyper.
While some experts do stand by this common belief, other professors claim that the majority of scientific research has concluded that sugar does not cause hyperactivity in youngsters.

11. Humans have five senses.
This is correct, although in actual fact there are at least nine senses and most researchers think there are more like 21. The five main senses - sight, sound, touch, smell and taste - are the ones referred to in this popular saying.

12. Fortune cookies are a Chinese tradition.
Fortune cookies were originally the invention of Japanese-Americans before being widely adopted by Chinese culture.

13. Sushi means 'raw fish.'
Sushi actually translates as sour-tasting.

14. Vikings wore horned helmets.
While this may well be true, experts say there is actually no evidence to suggest that Vikings ever wore horned helmets.

15. The forbidden fruit mentioned in the Book of Genesis is an apple.
The bible never mentions the forbidden fruit was an apple.

16. Vitamin C is an effective treatment for a cold.
Flu-sufferers are often encouraged to increase their dosage of Vitamin C, but most experts have stated that there is little or no evidence that the vitamin can help treatment of a cold. Instead of effectively treating a cold, it is thought to help build up the immune system to ward of potential flu viruses.

17. Penguins mate for life.
Penguins are mostly monogamous, but there are some species such as the Emperor Penguin which are serially monogamous. They mate with one couple for the whole season but will probably mate with another penguin the following year as the urgent need for breeding will make them avoid waiting for the same couple.

18. Caffeine dehydrates you.
While caffeinated drinks may have a mild diuretic effect - meaning that they may cause the need to urinate - some experts believe they don't appear to increase the risk of dehydration.

19. When in London, you are never more than six feet away from a rat.
This could well be true but hasn't been proven and is just a rough estimate as rodents are not evenly spread apart.

20. There is a dark side of the moon.
As the Moon is constantly rotating on its own axis, there is no area of the planetoid which is in permanent darkness.

21. A toilet's flush will change direction depending upon which hemisphere it is in.
The real cause of 'backwards'-flushing toilets is just that the water jets point in the opposite direction.

22. Mars is red.
The red color we see in images of Mars is just the result of iron rusting.

23. Sunflowers track the sun across the sky.
A common misconception is that sunflower heads track the sun across the sky when in full bloom. The uniform alignment of the flowers does result from heliotropism in an earlier development stage, the bud stage, before the appearance of flower heads so technically they follow the sun before they have bloomed, not after.

24. People use just 10% of their brain.
Neurologists describe the myth as false and state we use virtually every part of the brain, and that (most of) the brain is active almost all the time.

25. Your fingernails continue to grow after you die.
The dehydration of the body after death can cause retraction of the skin around hair and nails, giving the illusion that they have grown. However, all tissues require energy to sustain their functions, and no such thing is possible once the mechanism that promotes normal growth shuts down at death.

26. Bats are blind.
Despite the tiny eyes and nocturnal lifestyle, none of the roughly 1,100 bat species are blind.

27. Dropping a penny from the Empire State Building would kill someone.
A penny only weighs about a gram and it tumbles as it falls. Because of the tumbling and the light weight, there's so much air resistance that the penny never really gathers that much speed before it hits its terminal velocity. A gram of weight travelling at a relatively slow speed might hurt a little if it hit you on the head, but it's not going to kill you.

28. Handling a baby bird will make its mother reject it.
Most birds have a very poor sense of smell, so in most cases are unable to even notice human scent on baby bird.

29. You need to wait 24 hours before reporting a missing person to the police.
There is no rule that states you have to wait 24 hours before reporting a missing person. The person will be recorded as missing and their details made available to other police forces within 48 hours.

30. Your blood is blue before its oxygenated.
While many believe that de-oxygenated blood is blue, it is actually a myth because human blood is always red - although the level of redness does differ depending on how oxygenated it is.

31. A goldfish has a memory span of three seconds.
This is not true as goldfish do actually have very good memories for fish. They can be trained to respond various ways to certain colors of light, different kinds of music and other sensory cues.

32. You need to wait an hour after eating before you can swim safely.
As with any exercise after eating, swimming right after a big meal might be uncomfortable, but it won't cause you to drown. However, it is good advice to stay out of the pool right after a big meal as the digestive process does divert the circulation of the blood towards the gut and to a certain extent, away from the muscles, meaning swimming could feel harder.

33. Bulls are enraged by the color red.
It is a proven fact that bulls only see blues and yellow. They only react to the red cape because of the movements that flutter around.

34. Seasons are caused by the Earth being closer to the Sun.
As Earth orbits the sun, its tilted axis always points in the same direction. So, throughout the year, different parts of Earth get the sun's direct rays.

35. Eating lots of chocolate will make you break out.
There is no concrete evidence that suggests eating more chocolate can cause acne.

36. Shaving your leg hair will make it grow back quicker.
Many believe shaving body hair makes it grow back quicker but shaving hair doesn't change its thickness, colour or rate of growth. Shaving facial or body hair simply gives the hair a blunt tip which might feel coarse or 'stubbly' for a period of time as it grows out.

37. Frankenstein was the name of the monster in Mary Shelley's book Frankenstein.
Frankenstein was the name of the monster's creator.

38. Microwave radiation can cause cancer.
Most experts say that microwave ovens don't give off enough energy to damage the genetic material (DNA) in cells so they can't cause cancer.

39. Men think about sex every seven seconds.
While some men might think about sex this often, there is no real evidence to support this statement.

40. Ostriches bury their head in the sand when they are scared.
Ostriches swallow sand and pebbles to help grind up food in their stomachs. This means they have to bend down and briefly stick their heads in the earth to collect the pebbles. It is not because they are scared.

41. Waking sleepwalkers harms them.
Waking a sleepwalker won't cause them any physical harm but but could leave them startled or disoriented which is why many people believe it is best not to disturb them.

42. Albert Einstein failed math at school.
He failed one entry exam to a school but in fact, he actually excelled at mathematics throughout his schooling and even considered becoming a mathematician for a time.

43. Salt water boils quicker.
The salt water requires more exposure to the heat in order to boil than water alone, so the boiling point is elevated and the time it takes to get the water to boil increases.

44. Carrots help you see in the dark.
Carrots contain vitamin A, or retinol, and this is required for your body to synthesise rhodopsin, which is the pigment in your eyes that operates in low-light conditions. If you have a vitamin A deficiency, you will develop nyctalopia or night blindness. Eating carrots would correct this and improve your night vision, but only to the point of an ordinary healthy person - it won't ever let you see in complete darkness.

45. Houseflies only live for around 24 hours.
The adult housefly can live up to one month in the wild.

46. Eating cheese before bed will give you nightmares.
Cheese is believed to give you more emotionally charged dreams but not necessarily nightmares.

47. The capital of Australia is Sydney.
The capital of Australia is, in fact, Canberra.

48. Tomatoes are a vegetable.
Tomatoes are a fruit

49. Going out in the cold with wet hair will make you sick.
There is no evidence to support this; it is regarded as an old wives' tale.

50. Alcohol keeps you warm.
Alcohol may make your skin feel warm, but this apparent heatwave is deceptive. A nip or two actually causes your blood vessels to dilate, moving warm blood closer to the surface of your skin, making you feel warmer temporarily. At the same time, however, those same veins pumping blood closer to the skin's surface causing you to lose core body heat.
