The poetry of bubbles

2 October 2014

To celebrate National Poetry Day we are taking a trip down memory to when Steve Evans’ lecture on the Physics of Bubbles inspired a young writer to produce the following:

The Physics of Bubbles and their Applications
Prof. Stephen Evans

(Apologies to Gilbert & Sullivan)

Our lives were sadly lessened were it not for the ubiquity
Of bubbles’ different sizes and their wonderful proclivity
To soapily distend and gently wander on the air’s soft tide
But scientists are well aware that bubbles have a darker side!

The propeller of a liner they can chew in wide eyed innocence
Then cheery light emit as they subside in sonoluminscence*
But all’s not lost ‘cos bubbles have potential that’s deflationr’y
To dock on nasty tumours which are growing but are station’ry.

For bionanotechnophiles and medicos molecular
Are striving in laborat’ries to conjure quite spectacular
Bubbles that can vary from the micro to the nanosize
Bubbles that will heal you, I’m sure that comes as some surprise!

They’ll travel round your body like a little roving limpet mine
To lock on nasty ailments is their mission and their whole design
And when they come upon a growth that they have chosen to deflate
Then with a blast of ultra sound the tumour they will detonate!

They’re not the Guinness bubbles that you find atop your creamy stout
They’re not the yeasty lipids that in Champers struggle to pop out
They’re not the South Sea version that will make your shares disintegrate
But, by ingenious paradox, expand to discombobulate.

So here’s three cheers for bubbles, let us raise a glass and evervesce
And may the back room boffins with their cunning plans have great success!
So look afresh at bubbles when you’ve drowned a glass to quench your thirst:
Remember that ‘the first are last’ and don’t forget ‘the last are first’.

*(poetic licence with spelling: ‘sonoluminescence’)

By Graham Clarke
