Every time we think we understand the world, something new comes up to remind us that there’s still a lot to learn. For instance, coffee is one of the most famous beverages in the world. More than 400 million cups of coffee are consumed every single day. But did you know that caffeine does not actually give you energy?

The reason why we feel the burst of energy after a few cups is because it blocks special receptors in our bodies. Just like this, we have gathered some amazing facts that reveal a lot about the world we live in. But, before we begin, make sure to subscribe and hit that bell.

1. Cats are capable of recognizing their owners’ voices but choose to ignore them on purpose.

While we treat them as part of our family, they can appear quite rude when they ignore our commands. Most of us simply brush it off and assume that they just don’t understand. A study conducted by the University of Tokyo however, found out that not only are felines capable of recognizing their owners’ voices, but they purposely choose to ignore them.

2. There is a lake in Australia that is naturally pink in color.

Spanning about 600 meters (2,000 feet) in length by about 250 meters (820 feet) in width, Lake Hillier is a pink-colored lake on Middle Island in Western Australia. For decades, scientists tried to understand exactly what gave the lake its pinkish color.

In 2016, scientists made a breakthrough when they discovered that the presence of ‘extremophile’ microbes contribute to the lake’s unusual color. The pink color of the water is a permanent characteristic and even when the water is transferred to a container, it does not change its color.

3. Mosquito repellants don’t actually repel anything. They simply hide you by blocking the mosquito’s sense of smell.

The pesky critters are hard to evade, so we seek shelter from them by using repellants. But, did you know that mosquito repellants don’t actually repel anything? Mosquitos rely mainly on their sense of smell. This is why some people are more attractive to mosquitos than others. When we use mosquito repellants, the DEET (thediethyltoluamide) which it contains evaporates on the skin and blocks a mosquito’s sense of smell; thereby preventing it from finding its target.

4. Dogs sneeze when they are playing to remind their playmate that it’s just play and not a true fight.

Most dog owners have witnessed their canine friend sneezing while playing with other dogs. Experts believe that the sneezing is actually part of a set of communication tools that dogs use to signal cooperation, warning, deference, or an invitation to play.

While playing, the sneeze is believed to be a gentle reminder to their playmate that the scrimmage is just play, and not a true fight. Most dogs sneeze just as the play starts to escalate or become more intense. Experts believe that the sneezing method is a cue to the playmate to keep things fun, light, and safe.

5. The revolving door was invented by Theophilus Van Kannel, who disliked the social convention of holding doors for others.

It is considered a common courtesy to hold the doors for others behind you. Theophilus Van Kannel, however, disliked this idea so much that he went on to invent a new type of door where no one has to hold the doors for others. The Philadelphian resident patented the idea for the revolving door on August 7, 1888, and the world’s first revolving doors were installed at Rector’s, a restaurant in Times Square, in 1899.

6. Friends are more similar genetically than strangers.

According to a new study published in Proceedings of the National Academy of Sciences, unrelated friends have 1% of genes which match. This is likely because we are naturally inclined to gravitate towards people that we have something in common with.

7. Caffeine doesn’t actually give you energy. Instead, it just makes your brain think you’re not tired.

For some of us, caffeine is the only thing that gets us throughout the day. While we think that drinking coffee gives us a boost of energy, it actually does not. Studies show that caffeine just makes our brain think that we’re not tired.

Once caffeine gets into your blood stream, it reaches the receptors in your brain that usually host adenosine; a compound that builds up in you the longer you’re awake, in order to tell you when to sleep. The caffeine then masks the adenosine in your system, making the brain think that you are no longer tired and in need of sleep.

8. A cumulus cloud weighs about as much as 100 elephants.

Despite their light and fluffy appearance, clouds are actually pretty heavy. Researchers have calculated that the average cumulus cloud that we see on a sunny day to weigh an incredible 500,000 kg or 1.1 million pounds.

If a cumulus cloud contains 500,000,000 grams of water, or 1.1 million pounds, that cloud weighs about as much as 100 elephants. Although the clouds weigh millions of pounds, the reason why they float is because the weight isn’t concentrated, but rather distributed among trillions of really tiny water droplets.

9. The average office desk has 400 times more bacteria than a toilet seat.

A study conducted by Printerland in the UK found that one in every 10 office employees never cleans their desk. This allows dangerous bugs to thrive.

The study also showed that an average desktop harbors 20,961 germs per square inch, and that’s in addition to 3,295 on the keyboard, 1,676 on a mouse and a staggering 25,127 on the phone. At the same time, only 49 types of germs were discovered on an average office toilet seat.

10. If you ever feel like someone is looking at you, then your feeling is probably right. Our brains have “gaze detection”, which senses when someone is staring at us.

Have you ever walked through an unfamiliar neighborhood and felt like someone was staring down at you? Even if we brush it off as just a feeling, it’s most likely true. Our brains have “gaze detection” that responds to us being observed by someone unfamiliar. Studies show that when the observer’s gaze is averted just a few degrees to the left or right, our brain cells do not respond. Scientists believe that the ability could be an evolutionary trait that helps us avoid potential danger.
