The lightning had began and the nightly deluge would soon descend.

It was then that the lightning began to fall.

About eleven o'clock lightning began to blaze continuously in the sky.

Now, as they watched, lightning began to flicker and spark within the clouds.

Then the lightning began to strike in the trees nearby, with cracks so loud that it made her head ring.

"Next we want to find out how lightning begins and forms."

She didn't answer, but the lightning was beginning to flicker across her fingers again.

Then the lightning began striking so low that they had to duck their heads.

And very soon the lightning did begin in spectacular earnest.

Thunder and lightning begins when the top of the cloud is 25,000 feet (7,280 m) high.
