If you are really bored, you can cause lightning:

"A lightning rocket is a rocket that unravels a conductor, such as a fine copper wire, as it ascends, to conduct lightning charges to the ground. Lightning strikes derived from this process are called "triggered lightning."[1][2][3]"

Of course, you can just drop some HE instead. Not sure how much damage lightning actually does.
