Today, we all Know about the covid-19 news better known for coronavirus.
It's something that we can see daily in news and Tv's .Due to this most of the countries converted into lifeless place because of lockdown announced by government of different countries. The WHO Announced in early March 2020 that the virus was now at a pandemic stage across the world .
What does the word 'pandemic' Exactly mean? and How this is different to an outbreak and Epidemic? These questions often arises in the minds of people so let's find out
What is an outbreak?😧 
Generally speaking, the term 'outbreak' can be summarized as a small, but unusual burst of disease. An outbreak is usually What is used to refer to a geographically
contained spread of disease. so when we look at coronavirus, the initial cases that were founded in china would have been classify as an outbreak.
What is an Epidemic?😰 
An Epidemic constitutes an illness, disease or virus that is growing in reported cases and spreading internationally. In simple words when virus goes from domestic to internationally then situation shifted from 'outbreak' to 'Epidemic' . When we compare with present scenario looking at covid-19, when cases in china started rise exponentially and we started seeing that virus now spread from china to other countries then situation shift from 'outbreak' to 'Epidemic'.

A Pandemic is defined as being present globally and spreading out of control.
so when The WHO declared that covid-19 to be at the stage of Pandemic, it shouldn't be surprised for people because virus had spread to 170 countries and territories in total.

4.How many Balloons Does it take to Float a Human in air?😏
Floating into the sky with the help of clusters of balloons is the childhood dream from many children. But put this into the Real Life Circumstances, is it even possible? 
There's a science in everything, even in Balloons!
As we all know that Helium Gas is filled in the Balloons . Helium is strong enough to lift one gram per litre of helium .So if Balloon has 5 litres of helium it means that balloon can lift 5 grams. But When it comes that How many Balloons required to float yourself. you have a few options and i.e USE OF THOUSANDS OF SMALL BALLOONS , OR HUNDREDS OF HUGE ONE.
so, The average human weight is 137 pounds for that you would need 5000 standard balloons and almost 58000 litres of helium.
If you want to use the small amount of balloons than you can use Jumbo balloons of 36 inches. Although, you need same amount of helium but you can manage with 145 Jumbo balloons . Even then you can yourself off the ground. If you want to TRY! Then you can TRY at your own RISK!
3. Can you Reach the END of the Rainbow?😅
Sometimes our mind thought Is their any end of Rainbow? or Can we Reach the end of the Rainbow? These Questions came into our mind after we saw the Rainbow. so. Let's Crack these Questions.
Sadly, You will never reach the end of the Rainbow Because rainbows are actually optical illusions rather than something physical or tangible. A rainbow is formed because raindrops act like a tiny little prisms and raindrops refract and internally reflect the light of the sun towards you look at them. Different wavelength of light refract at different angles, so the sun's white light is divided into the orderly set of huge arcing colors you see in rainbow.
So, with this in mind it make it fairly logical sense that when you move towards a rainbow, the angles you are viewing it through change.
Rainbow Will always be the same distance away from you. As you move towards the rainbow , it will always be the same distance away from you , so you can never reach it.
for a rainbow to remain constant, the angle between the sun, the droplet , and the observer has to be at 42 degrees.

- Sun Positioning (Using Sunrise and sunset)
- Star constellations( Birds which are travelling in night they determine the path with the help of stars they learn the constellations and navigate by them, The north star is the most Important as its in a fixed location, but all constellations are important are useful in figuring out time and location)
