SUMMARY:

• The burning sensation you have in your mouth after eating chili peppers is caused by a particular chemical compound in them.
• If you think your cat loves to catch some Z's, what will you say about koalas? These marsupials sleep from 18 to 22 hours a day!
• Have you ever got chills while listening to music? It was your brain releasing dopamine - a chemical compound that causes pleasure.
• Continental plates keep drifting at the same speed your fingernails grow. An underground activity that makes them move also causes volcanic eruptions and earthquakes.
• You've probably noticed that the colder it is outside, the louder the snow crunches under your feet. It happens because when the snow compresses, teeny ice grains rub against each other.
• Just one bolt of lightning will provide enough energy for a two-slice toaster to work for 84,000 minutes.
• Roosters can be exceptionally loud, and the question is, "How do they not go deaf if this thundering noise is coming right out of their beaks?" Simple - they have a natural mechanism that works as built-in earplugs!
• The very first helicopters had wooden rotor blades. At that time, fiberglass hadn’t been invented yet, and wood was the best available material: strong, lightweight, and fatigue-resistant.
• Dogs can distinguish way more smells than humans. But when it comes to tasting something, people win hands down.
• Astronauts in space have to work out no less than 2 hours a day to keep their bodies strong.
• At any given moment, around 2,000 thunderstorms are happening in different places on Earth. And if we add up one full year, this number will be more than 16 million!
