How to Stop Our Eyes From Being Irritated While Cutting Onions?

How does onion burn our eyes while we are cutting it? The answer is interesting. There are two kinds of enzyme in onion. The first named as alliances and second as lachrimatory factor synthase (LSF). There is also an acid called as amino acid sulfoxides. While we cut the onion we break the cells of onion. The enzymes and acids that were kept separate inside the cells begin to mix up with each other. The first enzyme helps to convert amino acid sulfoxides into sulfenic acids. Then LSF treats with sulfenic acid to produce Syn-propanethial-S-Oxide. This reaches to our eyes and reacts with the waters or moistures present in our eyes. This interaction produces sulfuric acid which produces a burning sensation in our eyes and this signal is carried up to brain through a sensory neuron called as ciliary nerve. Then brain again signals lachrymal gland to produce tears in a huge amount so that the acid will go out and the irritation would stop.

There are many ways to stop our eyes from being irritated while cutting onions………They are…..

(a) Before cutting the onions cut it into two or four halves and dip inside water for some time. The enzymes of onions are water soluble so, they dissolve in water. This will prevent the reaction between enzymes and acids which will prevent our eyes from burning and being watery.

(b) Use sharp knife to cut onions. Enzymes are released when we cut them by breaking their cells. This will apply more pressure (since the area will be small) so the cells will be sliced rather than being crushed down and spreading which will stop mixing of chemicals and so on.

(c) Chop the onion very fast. Due to inertia the enzymes and cells remain at the same position which prevents the mixing of enzymes and acid. It will occur so fast that the gas will not get too much chance to touch our eyes.

(d) Put the onion in freezer for some time before you cut onions. The enzymes will freeze so there is less chance of mixing of acid and enzyme.

(e) Burning candle around where you cut onion is also a way because the acid emitted will go towards flame although it is not much effective all the time.

(f) Wearing swimming goggles prevents the acid from going towards your eyes and you will not find it burning. This is the most effective way.

(g) Use fan during you cut onions. This will blow the acid away.

(h) Sing a song or simply blow air from your mouth while cutting onion. This will also blow the acid away.

(i) Spray some water in your chopping board and cut the onions. The mechanism works as the first on.

(j) Cut the root at last because you will find more acid over there which is enough to burn your eye badly.

(k) Cut more onion as you can. This will develop your eye in such a way that it will find its way to protect against the acid.

(l) If you have a clean cloth then make it wet with water and cut onion above that surface.

(m) If you have practice you can close your eyes and cut the onion.

There is also another device that you can make in your home if you don’t have swimming goggles………I created it like this………..



Take a box like this.


Cut its three sides from middle in this way.



Paste a hard and transparent plastic in it.


You can keep it like this.



Decorate it if you want.



Put elastic as shown above.


Cover it from back side and put button on one end side of it.

Note: You have to bend a little bit while cutting this so that that will be comfortable for you.

Devastating Chilly: Affecting Mechanism in Tongue and Stomach

We all people need food for getting energy. We need different food products for this process. Adding some hot and spicy taste to that food increases our feeling a little bit. The many foods such as chilly and other products are there to add that kind of feeling. But the first curiosity is, ‘’Why do we feel hot due to chilly?’’ It’s very interesting. It’s due to capsaicin. Capsaicin is known as the member of vanilloid family. Vanilloid are compound containing vanilloid, vanilloid acid, capsaicin, homo vanilloid acid etc. While we eat chilly, capsaicin comes in contact with our tongue than it interacts with the sensory neurons of tongue. Capsaicin is the member of vanilloid family so it goes in contact with receptor vanilloid receptor subtype 1 often referred as TRPV1. It is stimulated with heat and physical abrasion. Capsaicin gives just a normal heat to tongue. A small change occurs in trpv1 known as depolarization which is due to the capsaicin. It feels as a very hot substance has touched it. So it signals to the brain saying that its very hot. But in real it’s just normal and is tricking our mind. So chilly tastes very hot. There is also one effect of it, which is stomach burning. There are many small lining in the stomach. And when capsaicin interacts with then it burns our stomach. There is also another explanation about it. In my view the inner organ that is stomach is very sensitive like a wound. If we even touch a wound gently then it hurts and more than that, if we give it a feeling of heat then it will give us vigorous and bad feeling. Like that capsaicin gives stomach a small feeling of hotness and its sensitiveness makes our stomach burn.


After we feel hot due to chilly most of us may have a common feeling of drinking water. We drink water thinking that it will remove hotness but no any change occurs in it except for one or two second. In real the nature if capsaicin is to dissolve in oils or fat products such as ghee, milk etc rather than in water.

For explaining this I had done an experiment. You can try this at your home too. The explanation of the experiment is…..

(a) Take two cups of equal size and volume.
(b) Fill one-third part of one cup with water and again fill one-third of another cup with dairy products such as milk or cream.
(c) Add equal amount of chili powder or sliced chilly in both of the cups and stir it nicely.
(d) After stirring, taste the two solutions at certain interval of time.


In conclusion you will find that the solution of water and chili powder will taste hotter than that of solution of milk and sliced chilly. This activity demonstrates that the water has no any effect on capsaicin and it goes worth drinking water for getting rid of hotness caused by chilly. So we should always use dairy or fat containing products such as milk, cream, butter, ghee, bread with oil, etc to overcome such hotness.

Why Does Fire Glow Brighter When we Blow Air?

There are many spectacular phenomena we see in our daily life. We just see it, know it, take it as a memory, as knowledge, practice it daily and still don’t know the actual reason behind it. We should try to know the actual science behind every phenomenon we see in our daily life. Not even a single moment of our life is out of science.

Well now let us discuss about the glowing fire which glows even brighter when we blow. Isn’t it strange? Every one of us knows that we take in oxygen and give out carbon dioxide.  We have been learning this since our childhood, may be since 1st or 2nd standard in our school. We take in oxygen for oxidation of food to release energy in the form of ATP (Adenine Triphosphate). Oxygen is required by each and every cell of our body for cellular respiration.

Oxygen reach to each of the cell in the form of oxy-hemoglobin complex and carbon dioxide is released from there in the form of carboxy-haemoglobin complex. Use of oxygen is not limited just for our body but also for ignition (burning). Without oxygen, fire is nearly impossible. Oxygen is good supporter of burning but not itself a combustible gas. On the other hand, carbon dioxide is neither combustible nor a supporter of combustion. It is a good fire extinguisher instead.

Whenever carbon dioxide is exposed to fire, it forms a blanket around the fire stopping the oxygen to reach to the fire to make it burn continuously. This is added up by the weight of carbon dioxide being more than that of oxygen and other atmospheric gases. It can hence extinguish the fire relentlessly. Now, the confusion can reach to the peak. We exhale carbon dioxide which is a good fire extinguisher. Despite this fact, the fire glows brighter when we blow. I do not recommend you to go and try it in case of a burning candle. It will surely go off. We all have at least once tried it in case of fire on logs or woods.

Let me now explain you the actual reason behind it. The pressure difference created by the blowing carbon dioxide near the fire plays the role. The blowing carbon dioxide having greater velocity than the atmospheric air causes to lower the pressure of air near the fire, given by Bernoulli’s theorem (pressure is inversely proportional to the velocity). This pressure difference causes nearby atmospheric air to rush towards the fire. As I have mentioned that oxygen is very good supporter of combustion, with such large amount of oxygen being rushed towards fire, it glows with significant brightness. Another question may arise in your mind, why we see using a hollow, narrow pipe to blow the air in fire? It is favored by Bernoulli’s theorem and equation of continuity followed by principle of conservation of mass.

When air enters through a narrow pipe, the area of cross-section decreases so that the velocity of air increases, given by the equation of continuity (area of cross-section is inversely proportional to the velocity). It can be observed better in case of liquid. As the velocity increases, the pressure decreases, given by the Bernoulli’s theorem. As there is smaller cross-section in a narrow pipe, there is greater velocity leading lower pressure. To balance the difference in pressure, there is greater chance of rushing of oxygen towards fire to make it glow brighter. This is the reason behind using hollow, narrow pipe for blowing the air in fire.


Then why doesn’t this work in case of candle? Actually, the burning candle does not have enough surface area of ignition to favor this phenomenon. When carbon dioxide blows towards candle, immediate blanket is formed which blocks the passage for oxygen within a moment to turn off the fire. However, in case of fire on wood or logs, the fire has greater surface area which cannot be easily covered by the amount of carbon dioxide we exhale from our tiny lungs. But of course, if we blow carbon dioxide in extent enough to form a blanket around the fire, then any sort of normal fire we use in our daily life can be extinguished. I personally recommend you to experimentally try this and conclude on your own for deeper and clearer idea about what I have just explained.

Footprint of Lord Krishna in Kathmandu Valley

Kapurdhara is one of the busiest place of Kathmandu city.  It's a destination of several internal and external tourists due to its historical, social and geographical background. But it's rarely mentioned somewhere that this place carries the history of Lord Krishna's arrival in the valley. This place records footprint of Lord Krishna in Kathmandu.

Graving Blog
5 thousands years ago, the current area of Kapurdhara, Kathmandu lacked water for survival. Lord Krishna, who had come from India, shot with bow and arrow on the ground and then it brought white water from there. The water was as white as camphor {Kapur}. A tap {dhara} was also established there. So the place is called Kapurdhara which means a place where a tap having white water as camphor is found.

9 Types of Words That You often Pronounce are Badly Incorrect

English is the international language of the world. It has brought all to the men into one single garland. Today the knowledge of English is a must to explore the world, maintain personality and lead a professional life. So interaction through English is common in our surroundings. But what happens to our intellectual level if we pronounce our words mistakenly? Have we ever thought on it?

Below are some of the common words I caught being mispronounced in my surroundings and they have been made correct here:

1. wednesday- adjective
‘d’ is silent.
2. practically-radically-enthusiastically
‘cally’ is pronounced as ‘kli’ not ‘kally’.
3. why-when-wheat-what
‘h’ is silent.
4. husband-Thursday
‘s’ is pronounced as ‘z’.
5. president-resident
‘si’ is  pronounced as ‘zi’.
6. account- alone -along -amount- arise- await- award- awake
‘a’ should not be pronounced as ‘e’.
7. business- darkness- kindness- helpfulness
‘ness’ is pronounced as ‘nas’.
8. hurtfully- helpfully- carefully 
‘fully’ is pronounced as ‘’faly’.
9. efficiently- sufficiently
ifisantly- safisantly

Some words are pronounced differently in British and American English. But the above written words are pronounced uniformly in both types of language.

The Important Message of Yesterday's Earthquake

5.5 magnitude hit Nepal yesterday at 10:05 pm. There is a common question among people, i.e., Was that normal?

According to Nepal Seismological Centre, it was a usual aftershock of Gorkha Earthquake rocked in April 2015. However, it shook not only the rupture zone but also many other parts of Nepal as well as southern India.

Though this aftershock does not carry any message of threat at present, its epicentre 'Sindhupalchowk' gives a signal that this area is storing energy enough to trigger several such moderate aftershocks in future. Because this area has experienced many aftershocks with the size of 5 whereas other parts of the rupture zone are facing jolts with the size of around 4 only.

Moderate aftershocks are similar to the miner aftershocks except the fact that they can destroy already damaged infrastructures. They may also cause injuries to the people who run in panic during the quake.

People nearby the aftershock zone should be given special caution training. General earthquake education should be given to the public so that they do not have to sacrifice their sleep for no serious reason like yesterday.

2 Secrets of India Earthquake That Scientists Did not Tell Us

This article is the second part of the article titled 'Is 8.2 Going to Hit India?'.

The Ministry of Home Affairs' {MHA} National Institute of Disaster Management {NIDM} has warned that the earthquake with the magnitude of 8.2 or greater is going to rock North India especially the mountains.

The experts have said that a series of earthquake of Manipur {India} in 2016,  Gorkha{Nepal} 2015 and Sikkim {India} 2011 have re-ruptured the already ruptured tectonic plates underneath the Himalayan region of India. Some international scientists even believe that recently rocked Manipur Earthquake is the sign that the stress has not been fully released which increased the chance of at least 4 earthquakes greater than 8 magnitude in the region.
Factually speaking, the tectonic plates of Nepal, Bhutan, India and Myanmar are interconnected. Though scientists reserve their arguments, there are some underestimated truths that can give some hopes which I would like to say Secrets of India Earthquake in this article.

Here scientists are talking about an earthquake caused by another one. But is there any known mechanism that has caused an earthquake to trigger another one in another place? Obviously not. The past observation says that the earthquake can trigger stress only over some hundreds of miles not thousands because the crust is not so rigid to facilitate stress transfer over thousands of miles.

USGS scientists say there is evidence that some major earthquakes manage to trigger stress much greater distances like thousands of miles but these triggered quakes are small and very short lived.

Another thing seismologists often talk is the record of accumulated stress on the fault which is recorded through the satellite camera. But the hidden secret which public is always confused is that it is not possible to make a direct measurement of stress on the fault. What scientists can do is measuring the stress of fault with satellite camera and then developing a model by integrating the record with the history of previous earthquakes on the fault which will give a rough idea where future earthquake is likely to strike.

In conclusion, there is no mechanism developed so far which can predict earthquake with definite magnitude and time. The only one thing scientists can do so far is the long term prediction which is a rough estimation and that should not be misunderstood.
