Bernoulli’s Principal
The wing, as I was always taught,
Is always asymmetric –
Flat beneath, but curved above,
To make the wind go quick.
You see, it has a longer route to travel
Over the top.
And thus it has to hurry-up,
And make the pressure drop.
And thus, the wing is sucked straight upwards,
Sucked into the air.
But what they never told me was,
Just why the wind should care ?
Do they all think we think that the wind is alive
When charging ahead ?
Suddenly rushing to rejoin its friend
That blew beneath instead ?
Oh, and when pressure is low, it still doesn’t suck –
It shoves, as before.
What keeps us up is simply the fact
That high pressure presses more.
In short, there is no welcoming wind
To lure us into the sky.
But clearly something’s working here,
For aeroplanes do fly.
