Suppose clouds had strings attached to them which hang down to earth. What would happen?

Isn't it called Lightning....you'll be in for a shock if you probe further in a storm :( 

Well  it could put a damper on nazi rallies - like you could grab the string and pull  the cloud over to their gathering and hope for rain. Cheers!

Rather related to Nanoose's answer, I'd pull a cloud (maybe more) down and keep it/them over me. I much more adore cloudy weather as opposed to bright, cutting harsh sunny days.

As far as the article, whether (weather, ha!) that leans me toward genius or psychosis, I don't know.

Most laws of physics would unravel, methink.

This would happen!

You'd pull on the string and the cloud would drop down, filled with blood. That's what happens when fluffy things have strings attached to them.

People would pull on the strings. We would end up with lots of fog.

Are you sure they are clouds, and not long-lost Zeppelins dangling their mooring cables just asking to get safely moored?
