Wana Dewliya Thurule – An all-time favourite Sinhala song

This tune is a tribute to all the Sri Lankans bravely facing this difficult time due to COVID19.

“Wana Dewliya Thurule” is an all-time favourite song by Indrani Perera, a legendary Sri Lankan singer in the 1970s. The song is about the exquisite frescos on a massive column of rock. Sigiriya is one of the world heritage sites with a grand historical and archaeological significance that draws thousands of tourists around the world every year.

Poem – The world outside your house

You see the sun shining,

The leaves are turning green,

Life starts to begin,

From winter, the Dark Age,

The park’s turn green and blossom,

But not a soul is seen today,

You look out of the window,

From your brick cage,

The mood in the street,

Is so low it’s hard to gauge,

The birds wake from their slumber,

Confused by the empty roads, When people usually bustle, run or simply stroll

The children in the flats,

Feel despondent as they stare,

To the world outside their house,

At what they could have enjoyed,

The air rushing through their hair,

A free bird, no longer trapped in a box,

But the lockdown stills continue,

A cruel master shutting the locks.

The world isn’t what it used to be,

People are finding it hard to see,

What can be done, what can be fixed,

What should we do to get this Curse nixed?

The answer is so simple, yet so hard to do,

Just stay at home, and we will come through.

This is my prize-winning poem in the school poetry competition

My Helicopter Animation: pure HTML, JavaScript & CSS

During the lockdown due to Coronavirus, I am spending plenty of my free time on coding.

I am pretty comfortable with HTML and CSS now. This animation is my own creation, using both HTML and CSS; I did use some JavaScript too make the two buttons work, though. When I get stuck, of course, the help is just within earshot – my dad, who is a coder himself.

I spent hours in making this – finally got it right, a few days ago. I hope you will enjoy it. I am going to explain on my YouTube channel as to how I made it.

Not too bad for an eleven-year-old, I suppose.

Please move the scroll bar to get the animation in sight and then, make sure you choose the size as 0.5x from the list at the bottom of the animation; otherwise, it may not fit into the frame.

DESTINY😃

A short story

The sun beat down relentlessly, not pausing to allow the long-suffering citizens of Xylem to take a break. They heaved and groaned to no-one in particular whilst they dragged haystacks, bricks and laundry across the town to the Chief Guard, who stored these items for the King’s disposal. More often than not, a riot would break out, resulting in a wholesome whipping for the guilty; surprisingly though, the city was so dull that people enjoyed seeing fellow members punished. The city was spiralling towards doom, and only the ill, greedy, miserable, haggard old king knew it. To prevent a rebellion, he kept this fact hidden and secret, brutally torturing those who realised the real situation.

But there was one, a young and smart servant called Joe King came to know of this. After uncovering the current situation by seeing the rapidly decreasing income of the land, Joe King was furious. The home country he had been born, bred and grown in was being destroyed by a corrupt king stealing the country’s revenue!

There was, however, a problem. Joe King knew his status, and as much as he opposed it, in other’s eyes he was simply a slave. A slave with no other purpose in this world but to clean dishes.

And so Joe King’s masterplan began to unfold. He was constantly in peril, afraid that any time a guard would come to his small shack and drag him to the dreaded torture room.

The rumoured punishment was to have your tongue ripped out.

At first, Joe King was cautious, spreading the word only to his closest friends, but the word spread quickly, and soon Joe grew bolder, collecting people for a rebellion. One of Joe’s closest friends was named Peters, who was looking forward to being a teacher at a school.

And yet the king sat in his plush throne, sipping wine, unaware of the imminent war.

Now even lords and aristocrats were beginning to take notice. Joe King was hailed wherever he walked, no longer a mere slave but a future warlord.

By the time Joe was convinced he had a sufficient army, it was October the 29th. The attack was planned on the 31st of October, just two days away.

During the collection of followers, Joe and his friends had painstakingly handmade swords, arrows and helmets for each of the followers, who were glad that now they would have a chance of winning the war.

However, amidst all this excitement, one grumpy old man by the name of Trump was annoyed. His perfect idea of life was a life where he got attention and was fawned over, like Joe King.

“What has that lad done to earn all that respect?” he spat every day, ignoring the fact that he was too cowardly to achieve the same feat of courage as him. “He’s just a pathetic, overrated slave!”

He spat the last word out in disgust as if it left a bad taste in his mouth. But then a sly idea formed in his withered mind.

“I’ll tell the guards, get my reward money, and run away while those fools get massacred!” he whispered gleefully.

Joe King had drawn his battle plan and had explained it to his secret army. He was mildly interested as he saw Trump enter the king’s courtyard with a rare smile on his face, but attributed it to late tax payment.

His troops were in order as the church bell sounded at 11’o’clock. In one hour, at the stroke of midnight, Halloween, they would strike.

At 11:30 pm, the tension was so dense; you could cut it with a knife. The plan was to divert the army into three groups. The first would circle around to the left of the castle, whilst the second group would perform a similar tactic, only but on right side of the castle. The third group, including Joe himself, would charge forward and attack valiantly in case there was a guard regiment on standby. They were never expecting an entire army.

As 12 struck, the third group charged forward, producing as much noise as possible to cover the sound of the other two stealthy groups. Their hopes were not doused as they saw the army, their adrenaline only raised, as the most incredible war in the Middle East began.

The 3rd group fought hard and swift, trained by Joe and ex-soldiers who had joined the rebellion. The other 2 groups formed a ring around the army, entrapping the king’s guards. The battle lasted for a day, and everyone had a duty.

Daring doctors were war medics, rushing on to the battlefield exposed as they saved the lives of injured and elderly citizens concocted potions and recipes to disinfect wounds.

A truce was called the next day by the king’s army.

Xylem was saved.

Now there is no need to explain all the tiresome facts and history after the victory, but I can say for sure that Xylem, with Joe King’s fair and just rule had become prosperous and wealthy. Unfortunately, Trump’s descendants were as mean-minded as him. One of his latest ones is named “Donald”.

The End.

Vegetable couscous salad

Couscous was a dish that originated in Maghreb . It remains a still very healthy and exquisite dish, and if cooked correctly, is delicious as well!

Here are the ingredients needed to make a top-class couscous salad:

  • 175ml of water, boiling
  • 1/2 carrot(optional)
  • 1/4 cucumber
  • 1/2 yellow pepper
  • 4 dried apricots
  • 15ml spoon parsley
  • 1 vegetable stock cube
  • 100g couscous
  • 1 medium tomato
  • 1 spring onion

Method:

1: Measure the couscous. After certifying that 100g of couscous is measured, pour it into a large bowl. Be careful not to spill any as once couscous is lost, it’s hard to be found!

2: Make the stock by dissolving a vegetable stock cube in the boiling water. Mix the water well to guarantee that there will be no solid pieces of cube left.

3: Pour the still boiling stock over the couscous. Make sure the measurements are right, or the consistency will be inaccurate

4: Mix the couscous and stock with a fork. The couscous should appear to have little dots on it. Leave the mixture away for 5 minutes while you prepare the garnish.

5: Dice the cucumber into small chunks. For the tomato, cut a regular zigzag line across the side, then twist the two halves separately to form a flower effect, like so. Or as demonstrated in the photo, you could just cut the tomato into chunks.

6: Cut the carrots and peppers into small chunks. Try to make them small and evenly sized to ensure a neat outcome.

7: Slice up the apricots into thin slices. These will add an exquisite sweetness to your salad, which will enhance the flavour.

8: Add all the cut vegetables, apart from the tomato, into the now set couscous. Make sure the couscous is neither wet (water is seen) or too dry (the couscous has clumped together). In this step, you could also add the parsley and the salt.

9: Now, snip the parsley to create a flower effect. To make this process easier, you can use a sterile pair of scissors, to snip the spring onion at both ends, like so. Leave the cut spring onion in cold water, to allow the cuts to unfurl.

Cut the spring onion on the lines shown

10: Mix all the vegetables together in the couscous, then pour into a plastic container. Finally, add the tomato(with the flower effect) and spring onion.

11: If necessary, heat the couscous in a microwave for 30 seconds to warm it up. THen present on a plate and enjoy!

Gyroscopic Phenomenon

Gyroscopes are very interesting tools, able to ‘defy gravity’ and seemingly remove the laws of gravity. When they’re not spinning, they act normally, but when they are, an incredible feat of balancing takes place:

This shows a gyroscope balancing precariously on the end of a knife!

The reason why this happens is because of angular momentum; When something spins, it is spinning in one direction (left or right, horizontally). This direction is always perpendicular to the axis it is spinning from – here’s a diagram to help you:

The reason the gyroscope is amazing at balancing is that when the speed of rotation reaches a certain point, it starts to exert a horizontal force, like gravity. Since the spinning disk will always be perpendicular to the axis, it will always stay upright is spinning!

To keep ships stable, these are implemented in them, to keep them upright in waves or winds. The gyroscope is usually spun by a motor. The gyroscope is attache to the vessel, so the gyro’s natural tendency to stay upright also affects the ship.

The Prehistory of Music

The history of music, as you would expect, dates back a long way. However, many people don’t know the incredible age of the art. On this musical and melodious trip through time, I shall now present:

Nothing.

Now you may be wondering – “Hey! Where’s that ancient instrument I was promised?” Well, evidence suggests that the first music was using biological sound outputs, or in simpler terms: singing, clicking, shouting, humming, whistling e.t.c. (basically your average pop-star, but a bit more… caveman-like. Now…the instruments!

The first music

The first instruments were woodwind or instruments that require an input of air in order to produce sound. Using carbon dating, scientists in   UlmGermany found a supposedly 35,000-year-old flute made (keep in mind it was made entirely by human hands) by a vulture’s wing bone.

I know it looks like wood but bear with me

The prehistoric age is considered to have ended with the development of writing, as history could then be written down. However, along with the age of writing, came the age of music notes. At that point, the first music was being written down.

Around 1250, Franco of Cologne invented a system of symbols for different note durations, which consisted mostly of square or diamond-shaped black noteheads. And then … one of the first music notations looked like this!

(I’ll give you a prize if you can play this. I can’t even read it!)
