Make Your Own Cloud in a Bottle

The other day it was damp and overcast early in the morning, with a hint of rain in the air. With my steaming cup of coffee, I sat myself down in front of the computer, hoping to get some work done while the kids were still peacefully in bed. And in my quest for simple science experiments which could be easily carried out at home, I chanced upon this interesting experiment in which you could make a cloud in a bottle.

Here’s how it works.

What You Need

  • A large mason jar
  • A rubber glove
  • A torch
  • Boiling water
  • Matches

The Procedure

  • Pour a little bit of boiling water into the mason jar – just enough to cover the bottom – and swirl it around a bit gently.
  • Seal the air into the jar by fitting the rubber glove wrist around the mouth of the glass jar such that the fingers point downwards towards the boiling water.
  • After about 10 seconds, insert your fingers into the glove and move it upward so that the fingers are pulled out.
  • Now light a match and drop it into the jar, covering its mouth again with the rubber glove. You will observe smoke forming in the jar and the water at the bottom will put out the lighted matchstick.
  • Again, pull out the glove by inserting your fingers into it. You will observe a cloud forming inside the jar. If you re-insert the glove, the cloud will disappear.
  • Shining a torch into the jar through the glass sides will enable you to observe the clouds better.
  • In about 5 minutes, the cloud formed will gradually disappear with the particles settling down at the bottom.

The Science Behind it:

Inside the mason jar, the warm air is full of water vapor molecules from the boiling water. When the glove is inserted into the jar, it occupies some space; pulling it out frees that space and cools the air inside the jar to a certain extent. The water molecules present attach themselves to the smoke particles emanating from the lighted matchstick, eventually condensing into droplets which form the cloud.  Every time the glove gets re-inserted into the jar, the air present within gets warmed up again and the cloud disappears.

After all, if there can be a storm in a teacup, there can also be a cloud in a bottle! :)

‘A Little Magic Can Take You A Long Way…’

The year 2016 marks the centenary of the birth of British novelist Roald Dahl, touted by many as the world’s number one storyteller and rightly so. To mark the occasion, the Oxford English Dictionary decided to add a range of new words connected to his writings to its ever-increasing repertoire of words – such as ‘splendiferous’, ‘Oompa Loompa’, ‘human bean’ and ‘Dahlesque’ amongst others (read more here). These reminded me of my favorites when it comes to Dahl.

Here are three of his classics, which I love to read even today.

‘It doesn’t matter who you are or what you look like, so long as somebody loves you.’

 (The Witches)

This fantasy novel for children elicited the following response from the judges who presented the author with the prestigious 1983 Whitbread Award for his work: “Funny, wise, deliciously disgusting, a real book for children. From the first paragraph to the last, we felt we were in the hands of a master.”

From the very beginning, this story had me chuckling at every other line. ‘Deliciously disgusting’ hit the nail right on the head – how else could you describe a tale that involved witches with claws in the place of finger nails, enormous-sized nostrils, blue spit and heads with no hair? Endearingly deliciously disgusting, I would say. Add to it the wonderfully done up illustrations by Quentin Blake and you have the perfect package of a story; a brave young boy battling England’s witches along with his Norwegian grandmother.

‘We must hurry! We have so much time and so little to do! No! Wait! Strike that! Reverse it!’

(Charlie and the Chocolate Factory)

Here is a kids’ story which is silly and fun, as well as dark and serious. Instances of silly and fun – pillows that are made of marshmallow and are edible, chocolate bars that are invisible and hence can be eaten right in front of the teacher in class, a swimming pool filled with fizzy lemonade and many similar objects that will invariably catch any child’s fancy. My younger one remarked the goodies in the story were quite similar to those of the virtual games he plays and was pretty excited to add a couple of new ones to the list.

Talking about dark and serious, one of the chapter’s names itself is ominous in a way; it is called ‘The Family Begins to Starve’ and goes on to talk about how Charlie’s family members are hungry, poor, destitute and cold. But then there are the chanting ‘Oompa Loompas’ – orange complexioned and green haired dwarves working in the chocolate factory who eat cacao beans; punishments perfectly befitting the bad behavior of the kids and pretty comical caricatures alongside the story to keep the kids laughing all through the read.

‘Somewhere inside all of us is the power to change the world.’

(Matilda)

In 2012, Matilda found pride of place in the top 30 all-time popular children’s novels in a survey carried out and published by the School Library Journal. The story revolves around the protagonist – Matilda Wormwood – who is a child prodigy; awe-inspiring, brilliant and unconventional all rolled into one.

Then there’s the much-loved Miss Honey who makes sure newcomers in her class feel at home; the nutty and supposedly wicked headmistress aptly named Miss Trunchbull; the girl with two plaited pigtails who goes by the name of Amanda Thripp and other amusing characters. The story of the little girl is heartwarming yet unpredictable; all in all, a compelling and creative tale which is both a bit funny and a bit sad, in ‘Dahlesque’s’ characteristic way.

Try as I might, I still find it hard to put down any of Roald Dahl’s masterpieces once I begin reading one of his novels. And this line continues to resonate with me even now, years after I read it first:
