Quite timely after our recent dusty experience!

Einstein was a clever man, it's true.

'Don't ever feel you must
Rid your windscreen of that dust.

You can do this quite astounding little trick!
You can brush and you can scrape
Any quite amazing shape

A hose would send the dust right down the drain!
Much better you conserve it!
You must know I deserve it!
I shall last until the next downpour of rain!'
