Some scientific discoveries came after long research and experimenting but many of them came accidentally. Accidental scientific discoveries proved to be a game-changer in today's life. So here are 5 incredible inventions that were discovered by accident. 1. Microwave oven The microwave oven was invented by Percy Spencer entirely by accident. He was working on "magnetron" , one of the components of radar equipment. He was amazed to see that candy in his pocket had melted.  Out of curiosity, he tried placing other objects near magnetron like popcorn, eggs, etc (He was standing at a safe distance, so as not to start cooking himself). Popcorn started popping out and eggshells started exploding, and for the first time, he came to know that eggs will explode in their shells if cooked in a microwave. Spencer realized the potential of his invention and designed more efficient and reliable food-cooking microwave ovens. The early models were not received much popularity due to t...

Did you ever feel a burning sensation in your stomach or the chest? If yes then let's read about acidity...   What is acidity? An acid called stomach acid mainly consists of Hydrochloric acid ( HCl) which helps to digest food like burger, fruits, rice , etc. So when this Hydrochloric acid gets produced in excess amount then it causes acidity . This Hydrochloric acid can reach up to your throat and can cause problems like heartburn ( a burning sensation in chest), acidity, and tons of stomach problems. The pH of Hydrochloric acid can range between 2-3 making it very strong acid which can even dissolve a razor blade. So here a question arises that how can we reduce its amount and maintain the pH of our stomach. How can we cure acidity? By taking an antacid we can cure the acidity. Let's understand a simple chemical equation ACID + BASE---------> SALT + WATER (HCl) + (Antacid) This above reaction is called a neutralization reac...

When you are traveling on a plane and suddenly lightning hits the plane. What will happen to you? Does your plane will dance or get crashed straight into the ground. Let's find... Lightning To find out the actual reason let's understand what is lighting... Lightning contains millions of volts of current that can reach up to 1 billion volts . When it falls then it is more heater than the surface of the sun. So how planes can easily escape from that deadliest strike. How plane escapes from lightning? The outer body of the plane is made up of aluminum which is a good conductor of current. So when lightning strikes on the plane, the high voltage current just passes through the outer body of the plane without entering the plane and finally get eliminated through the tail in the atmosphere. In very rare cases planes may catch fire. The last accident by lightning was reported in 1967 when the fuel tanks of the plane were burst by lightning kill...

Whenever you feel cold I will suggest you take 2 thin blankets instead of 1 thick blanket. But why?? Because 2 chocolates are always better than one, just joking:-):-) To understand this we first need to know about bad conductors of heat.                                          Image source-  Aumsum Time Bad conductors of heat Any object which resists the heat is called a bad conductor of heat. Air, wood , glass , etc all are said to be bad conductors of heat because they do not allow heat to pass through them. Why this happens? In a thick blanket, heat can easily escape through it not providing better warmness but when you take two blanket s, air gets trapped between the layers of two blankets ,and acts as a bad conductor of heat and does not allow it to escape.  If you sleep with more...

I am sure that once in your lifetime you have seen some insects walking on water without any issues but did you question yourself how did this happen? So you are in the right place keep scrolling!!   The actual reason In one word you can say it's due to surface tension . What's that? If you are a science student then you know that molecules of water attract each other from all directions but the molecules present in the topmost layer are not attracted equally in all directions because there are no molecules present above it. So this topmost layer experiences a force of attraction in the downward direction behaving like a spring. Insects have very very less weight. So when they walk on water their legs presses the water molecules and as result water molecules push them back creating a floating like condition. Moreover , their legs are also widely spread causing the equal distribution of the weight of insects on the water. Why humans can...

Finally answered!   As biology states that reproduction causes the birth of new offspring with some minor genetic changes. On this basis, scientists proposed a theory called proto chicken or proto egg theory. What is the proto chicken theory? At the time of dinosaurs, they give birth to an egg which gives baby dinosaur with minor genetic changes (some different traits from parents). So in the future, this baby dinosaur also gives birth to another dinosaur with some genital changes and this cycle goes on. So scientists believed that after 10000 years new species of dinosaurs took birth which is different from the previous one and looks like a chicken called proto chicken and it gives birth to another egg called proto egg which gives pure chicken which we see today. Here arise two cases:- When we take proto chicken gave birth proto egg then we can say chicken came first. When we take proto egg gave birth to pure chicken then we can say egg came first...

Do you ever wonder why we blink our eyes without noticing it? By the time you read these two lines, you blinked your eyes :-) But why?? Why this happens? As children , you have played a game with your friends to stare in each other eyes without blinking but your eyes soon start burning and water starts flowing , but why?? Because blinking provides lubrication and removes dust particles from your eyes. Each time you blink your eyelids secrets lubricative chemical in your eyes which provides nourishment and helps your eyes stop being dry. Why don't you see darkness while blinking? Your brain is smarter then you, it trains itself to ignore the darkness. On average a person blinks eyes in every 10 seconds and you don't have to tell your brain that " okay now blink " it happens automatically by your subconscious mind so as it ignores the darkness come in your eyes for just 450 milliseconds of just like it ignores your nose despite the fact ...

We all experienced it once in our lifetime that when we put our fingers or feet in water then our skin gets shrink in water but have you questions yourself why this happens?? History Before 1930s scientists believed that our skin absorbs the water like a raisin and get puffy but this was found wrong because later scientists discovered that people having dead nerve cells in the skin do not experience puffy skin even they have the same skin as other people have, the reason was something different but what was the actual reason?? Why this happens so? Scientists later found that our skin has a layering of chemicals called  sebum which helps our skin to get rid of water. You also see that when you wash your hands then water quickly gets away from them, this happens because of sebum. When you put your hands in water for a long time them sebum washes away from your skin and activates an autonomic nervous system reaction which causes your skin puffy. Why i...

If you are a human then surely you cry every time while cutting an onion and your eyes get irritated but why?? Reason: Why you cry while cutting an onion Onion has cells that release a compound called sulfenic acid. This acid gets to mix with the enzymes of onion and releases another gas called  propanethiol S-oxide. This gas gets mixed with the water present in your eyes and produces sulphuric acid. This sulphuric acid irritates your eyes and makes you cry . I s it harmful t o eyes ? No, it's very  common H ow can you stop tears while cutting an onion Dip the onion in water for 5-10 minutes before you start cutting it. Cut the onion nearby the running water because water will absorb the gas but I suggest don't do this because it will waste the water. Put the onion in the freezer for 10-15 minutes before you start cutting it. You can also wear goggles that cover your eyes fully and do not let gas come in your eyes. I wil...

You will guess it is a car, house or a phone but the correct answer is ANTIMATTER. What is Antimatter? If you're a science student then you know that every thing in the world is made up of matter and matter is made up of very tiny particles called atoms. An atom contains a nucleus having protons and neutrons and electrons revolve around it. PROTON- Positively charged NEUTRON- Neutral ELECTRON- Negatively charged Nothing new in it, but do you know Antimatter have just opposite properties in which PROTON- Negatively charged NEUTRON- Neutral ELECTRON- Positively charged Shocked?? Cost of Antimatter It's $62.5 trillions dollar per milligram (mg). This makes it most expensive thing in the world. Uses of Antimatter To treat cancer. To produce large amount of energy. For research purpose. Note -  Matter+Antimatter= Large amount of energy release.

The reason is very simple,due to release of nitrogen gas from your joints. . yes it is true!! We have a fluid between our joints called synovial fluid which lubricates our joint from wear and tear. So when you bend your fingers then there is change in pressure and this fluid releases gas bubbles. When this bubble strikes to your joint and burst then it makes popping sound. Sounds cool but wait?? It will take around 20 minutes to make your finger pops again.  Pro tip- If you have this bad habbit then leave it today coz it has very bad health consequences

Even wonder why you feel Milk or Tea tasteless after eating ladoo or chocolate. This is all game of your mind nothing else. Let's do an experiment dip your hand in hot water and then dip it into normal water. What did you feel?? You feel water as chilled and cold but actually  water is normal. Same happens when you eat ladoo ( take it as hot water) which is extremely sweeter and it sends a message to your brain i.e sweet,sweet , sweet...... and when you drink milk ( take it as normal water)  just after then it tastes plain and tasteless because it is less sweeter than ladoo and your brain consider it another sweet thing and does not respond to it. . but wait?? Add salt to milk and then drink it,you can immediately feel it's sour because it send a opposite and different message to your brain and your brain immediately responds to it...
