0:09:50 > 0:09:57.
0:10:05 > 0:10:07Hi, and welcome to Science Fiction.
0:10:07 > 0:10:10The show where we take the stuff you thought you knew about science.
0:10:10 > 0:10:13And reveal some shocking truths.
0:10:13 > 0:10:14Ahhhh!
0:10:14 > 0:10:17Today's question, when you're ready, BUD-E.
0:10:17 > 0:10:20BURP! Oh, sorry about that, I'm full of chips, so I am.
0:10:20 > 0:10:24Today's question comes from Serena in Reenascreena...
0:10:27 > 0:10:30Lightning occurs when a powerful electric discharge
0:10:30 > 0:10:34moves from one cloud to another, or from a cloud to Earth.
0:10:34 > 0:10:37Or from a cloud to my head!
0:10:37 > 0:10:39Lightning happens in places where the air is
0:10:39 > 0:10:41highly electrically charged.
0:10:41 > 0:10:46During thunderstorms, dust storms, near erupting volcanoes -
0:10:46 > 0:10:49or when vampires are just about to strike! Argh!
0:10:50 > 0:10:51Ugh!
0:10:51 > 0:10:54Now, lightning comes in many forms.
0:10:54 > 0:10:56Sheet lightning, fork lightning, bead lightning...
0:10:56 > 0:11:00And my very own personal favourite, grease lightning!
0:11:00 > 0:11:01# Grease lightning... #
0:11:01 > 0:11:03Professor, please!
0:11:03 > 0:11:06Sorry, love, I was just having an old boogie.
0:11:06 > 0:11:09Now, Serena, when lightning goes to ground
0:11:09 > 0:11:12it will generally take the shortest route possible.
0:11:12 > 0:11:14So, if you're up a tree, on top of a tall building,
0:11:14 > 0:11:17on the side of a mountain, in the middle of a thunderstorm,
0:11:17 > 0:11:21swinging a golf club, you're probably asking for trouble. Whoa!
0:11:21 > 0:11:23So, now you know lightning can sometimes strike
0:11:23 > 0:11:25in the same place twice.
0:11:25 > 0:11:26And if you hear otherwise,
0:11:26 > 0:11:29well, that's just a load of old science fiction.
0:11:29 > 0:11:31Wah!
0:11:36 > 0:11:39Is there someone making a fry out there, lads?
0:11:39 > 0:11:41I swear I can smell something cooking.
0:11:41 > 0:11:43SNIFFS It's toast, is it?
