Can you extinguish a candle without touching it or blowing it out?

If you can, knowing one more trick won't hurt

What you need:

Two candles, a glass, baking soda, vinegar, matchbox

What to do:

1. Light the two candies and set them upright on a table.

 2. Put a couple of tablespoons of baking soda into the glass.

3. Pour some vinegar. You'll see the mixture bubble Stop adding vinegar when the bubbles threaten to overflow

4. Let the bubbles settle down 5. Then tilt the glass over the candle. Don't pour liquid on the candle just hold the mouth of the glass near the candle flame.

What happens

The candle goes out. If you can't believe it, try it with the other one!


Baking soda and vinegar react with each other with blaster. A by-product of their reaction is carbon dioxide gas. The bubbles you saw earlier were all carbon dioxide that pushed the air out of the glass. The glass is now filled with the gas which settles in because it is heavier than air. When you tilt the glass over the flame you're actually pouring carbon dioxide over the flame! This carbon dioxide does not allow oxygen to get to the candle wick and the flame starves and goes out! In real life too some fire extinguishers employ carbon dioxide which is quite effective in putting out certain fires.

Here's how to watch a tornado safely

Tornados and whirlpools in nature are destructive. But we can observe them safely inside a bottle

What you need:

 A one-litre plastic bottle, a tab, a stopwatch

 What to do:

1. Uncap the bottle. Fill it almost to the top with water.

2. Clamp the mouth of the bottle with your hand and turn it upside down. Hold it over the tub.

3. Now, let go of the mouth of the bottle. Measure the time it takes for all the water to empty out into the tub.

4 Restart the experiment. Fill the water from the tub back into the bottle. Clamp down the mouth and invert it over the tub.

 5. Now, slowly, start moving the whole thing in a clockwise or anticlockwise circle. Keep doing this until you see a tornado forming inside the bottle.

 6. Leave the mouth open and time the water flowing out into the tub.

What happens

When you invert the bottle without swirling it, water slowly falls into the tub below.

But when you start moving the bottle in a circle, a tornado forms and all the water quickly empties into the tub below. The time taken in this case is far lesser Why?

If you don't swirl the bottle, there's a glug- glug sound as the water slowly falls into the tub below. This sound happens because air and water have to take turn passing through the bottles mouth. Air from the outside passes into the bottle to fill it and water from the bottle passes out.

But when you swirl the bottle and make the tomato, you allow the air and water t simultaneously pass through the bottles mouth How? The centre of the tornado is a hole, as it is in the form of a spiral or a vortex. This centre sucks air in and the waiter moves around it. Then the water falls into the tub below thanks to gravity. The process of emptying out of the bottle is much faster when the air and water move like this together. That's the beauty of the vortex.

Try blowing out a candle using a funnel and then turn its spout and blow. See what happens.

Things you need

 Lighted, candle, Funnel

What to do:

Light a candle and blow hard through a funnel whose mouth is held a little away from the flame. You will find that you cannot blow out the candle. On the contrary the flame bends towards the funnel


Blowing through the funnel reduces the air pressure inside it. The air from outside rushes into the funnel, causing the flame to bend towards the funnel in the process. The air sweeps along the inside of the walls so if the edge of the funnel is held close to the flame it will be blown out

If you turn the spout of the funnel towards the candle and blow from the other end, that is, the mouth, the flame will be extinguished. In this case the air is compressed in the narrow spout, and blows out the flame as it exits.

What is coding?

Coding, also referred to as programming, is the art of communicating with the computers, i.e. telling the computer what to do, and how to do it. This skill of communicating with the computers can be used to do some very cool stuff such as creating websites, apps, games, and tools that are in use every day.

The first forms of computers were invented to help us with basic calculations and accelerate the rate at which we could do heavy computation.

It's a language!

 Humans speak in different languages such as English, Hindi, Tamil, etc. But computers, on the other hand, speak in binary - 0 and 1.

Here's an example. The notation of the first three letters of the English alphabet in binary is as follows:

A = 01000001

• B-01000010

• C-01000011

To instruct the computer what to do, we need a translator that can act as an intermediary. This intermediary is the code. Code is a form of writing that is not binary, but is easy to learn and interpret, and is something the computer can understand. Depending on the requirement, this is done through programming languages. For instance, languages such as HTML CSS and Javascript are used for building websites while Java Kotlin, CB, etc are used for building mobile apps

What is software?

Software is a set of instructions data or programs used to operate computers and execute specific tasks. It essentially directs all of the peripheral devices on the computer what exactly to do and how exactly to perform a task.Software development is the connection to the Internet, process of understanding business Examples of web browsers include requirements, or the problem Google Chrome, Mozilla Firefox statement and writing program(s). It is generally a planned initiative that consists of various steps or stages that result and Internet Explorer in the creation of operational software This is primarily achieved through computer programming, which is carried out by a software programmer and includes processes such as initial research, data flow design process flow design, flow charts technical documentation, software testing, and debugging. Here's an example. A browser is a software that accesses and displays pages and files on the Web. Browsers require a connection to the Internet. Examples of web browsers include Google Chrome, Mozilla Firefox, and Internet Explorer.

Aryan Khanna Editor-in-chief and COO of The Grow Project

What role do you play as the editor-in-chief and chief operating officer of The Grow Project?

The aim of The Grow Project is to help students grow mentally, physically, and financially. This is a student-nun media production organisation where articles, blogs, podcasts, and many more related to finance and self-discipline are created by and for teens. We focus on issues such as procrastination, self-discipline, stress, and also finance-related topics such as cryptocurrency. The organisation's growth has been so rapid that we have about 10 departments today. As a COO, I assign tasks at the start of every day, and some work varies. I mainly do the administrative work, and implement ideas based on the inputs from the team. I also replace the CEO when he is not available for important meetings. As the editor-in-chief, I review articles, blogs, and social media posts, and revert to the writers if there's a need.

You also founded an organisation named Raahat. What is it about?

Raahat is the Hindi word for comfort. The basic idea of Raahat is to make people comfortable. It is a non-profit organisation that aims to solve global issues by raising funds. Raahat is a collaboration of Grow Projects and a website called Five Rights. The funds raised are transferred to the largest and the most trusted fundraisers in India for COVID-19. When the pandemic stabilises, we are planning to switch the funds to a different cause on an international scale.

What motivated you to bea public speaker?

 Until 2020, I was an academics-oriented person and wasn't into any extra-curricular activities. When my school time was reduced during the pandemic, I realised I had to get out of the monotonous scholastic cycle. I wanted to be more passionate and less restricted. This motivated me to become a public speaker. I wanted to make a change in people's lives and mindsets. I wanted to make them believe they can follow their dreams and passions.

What is your learning as a public speaker?

I observed that many people do not realise the talent they have, and so don't work on that talent. The same goes with public speaking. Public speaking doesn't depend upon grades or levels because it is an endless process of growth. I was once assigned to a public speaking club. I didn't know how anything worked there, so I worked hard to improve my speaking skills. And when I did, the entire club applauded me. That's what gave me the motivation, and led me to where I am today.

Do you think internships help people improve their skills?

Internships are learning experiences. I worked as an intern in Stentorians. It allowed people to voice their opinions and also write on various topics. It taught me how to produce an article regardless of whether it is a research or non-research topic. I also worked as a voice-over artist, which taught me a lot about voice modulation, and helped me with public speaking.

What are your other interests and hobbies?

I play quite a number of sports. I have loved swimming since I was six. Here, too. I worked hard to improve my skills, and even won a district-level competition. I love writing. I have been enjoying lawn tennis for the last four to five years.

Who's your inspiration?

 Many The first would be Harry B and Jocko Willink, who’ve achieved a lot. They inspire many young people. Then there are those you want to work with and are easily approachable. Riyad Maroof Hassan and Arnay Agarwal are two young authors I want to work with. The others include Roman, my dedicated. hardworking COO: Abhaas, our media team HOD; and Ronit, the most positive person I know.

What are your future plans? What is the one thing you would like to change in society?

I would like to change the narrow mindedness of people their prejudice against those from other races, the LGBTQIA+ community, and those with mental health concerns. I would also like to change the mindset of people who don't try again after failure.
