Adding video to channels (Timeshift) - requested by kulpims.

Okay, in school they always told us that lightning went from the ground to the clouds, but this doesn't look like that. At all. Anyone want to use the magical internets to edu-ma-cate us??

Woohoo! Thanks guys! My first top 15!

Not nearly as slow as this one:

getting kinda sick of the ads on all the new youtube stuff

Agreed. You can click the X to get rid of it though.

weird, getting no ad at all.

Yeah but you have to click the x.

Yeah I like that one much more, but still cool nonetheless.

It's amazing how nature can create things of such great beauty and artists still struggle to find inspiration.

Lightning goes both ways, like blankfist. There are some that jump from the earth to the skies and some that do the opposite, afaik.

There's some lightning that starts at the clouds and goes up. pretty wicked.

Yeah, the claim that lightning starts at the ground is very misleading. But the actual process is pretty easy to understand:

Lightning is not a one-way reaction. To make it as simple as possible, thing of it like a balancing act. Negative charge on one side, positive charge on the other. So, once the cloud has built up enough "charge" it essentially grounds itself to balance out the equation again.

What you see in the video is the cloud sending down "leaders" towards the ground. On it's way down, the majority of the power is sent down one or two paths which eventually hit the earth. That downstroke opens a channel for the powerful "return stroke" which is where the majority of the heat and power come from, but only because the return stroke slams all of it's power simultaneously into the already-created channel.

It is, in fact, the exact same effect as shocking someone by scuffing your feet across the carpet. You build up a negative charge (in this case, by 'rubbing' off the positive charge on carpet) and then you ground yourself by coming near someone else. When you come close enough you will exchange charges, balancing the charge again and creating a tiny bolt of electrify. Now magnify until you have a bolt that stretches about 1.5 kilometers to the ground, contains several hundred terawatts of power and reaches temperatures in excess of 10,000 centigrade... and you have a lightning bolt.


...did any of that help?

this one has sound too
