What Causes Thunder?

Ever notice a loud rumbling or crashing noise heard after a lightning flash? Well why exactly does that happen and should you be alarmed?

So jelly (jam) sandwiches aren't normal in the USA? Odd

Thank you. You know how you find yourself thinking "I wonder how this works". Today was how thunder worked because I'm in a thunderstorm right now. Thnx

Omg 1-a am watching this during a storm right now and 2- when she showed an example of thunder and lightning the lighting appeared at the same time 😂

[Trance_Kitsune]

...I guess I'm the only one who really enjoys jelly sandwiches..

[bunnykiller]

okay... if lightning occurs in a fraction of a second, then why does the thunder last for several seconds...??? ;)

Notice she don’t say “who would eat a peanut butter sandwich?” Cause they good asf

Put at 0.75 speed to have a regular pace at paying attention

TestTube 101 I'm not sure that you will reply, let alone see this but, I am really enjoying your new videos. They have a lighter tone to them and are very sciency in fun, easy to digest chunks. Plus the quality of the videos are great, keep up the good work.

0:20 Lightning is literally ripping through the air so aggressively that you can hear the thunder boom from miles away.

I heard thunder in my school hallway once, oh wait

[kechan_]

[saal]

u made me hungry, now I'm going to have peanut butter and jelly sandwich with cup of green tea, it's midnight 01:01 here right now ... Thanks for that 😿

[fionnabambalan]

That was fast but hey!! At least I learned something

[bbnnmm]

0:00 she said what the heck is thunder

[eybimey]

This is a pretty poor explanation of what thunder is. Lightning is an electrical discharge; it doesn't "rip through" anything, it's actually moving from particle to particle of the air itself. When it does this, though, it's delivering massive amounts of energy to the air particles it touches, and that heats up the particles in a split second. Hot particles move quickly and rebound off one another energetically, so the heated air particles spread apart from one another like billiards balls when they're struck, literally at the speed of an explosion. That explosion of moving air is what makes the sound of thunder.

So it’s as simple of lightning breaking the sound barrier causing a sonic boom
