00:03So cool! Science!
00:11Dear Crazy Chris, could you teach me about supervolcanoes?
00:15Okay, so check this out. I am going to show you how to make your very own volcanic model right
00:21at home.
00:22And no, I'm not, you know, going to make one of those...
00:26Models, you know, with the baking soda and...
00:30Vinegar...
00:31Of course it doesn't even make any sense, because volcanoes do not work on a chemical reaction.
00:39Instead, I am going to show you
00:41A, a model that is way more accurate, and D, way more delicious.
00:49You will need a brand new microwave! Actually, any microwave will do.
00:54And all you need to do this wicked cool model is your lunch.
00:58Yeah, a pot pie!
01:00Whoosh! Whoosh! Whoosh!
01:02That's it? Like, that's not spectacular.
01:05Well, hey! Hold on to your corn cob pipe there, pot pie!
01:09Because I'm about to lay an A-bomb on your grey matter!
01:13Well, yeah, by the way, do not put any punctures, holes, or cracks in your crust.
01:18Cracks in your crust?
01:24Okay, so check this out. The hot goo...
01:29Okay, so check this out. The hot interior cracks through the crust and flows over the land.
01:36Who would have thought you could learn science right there from your lunch?
01:39Okay, so what, what exactly is a super volcano?
01:43Well, don't look at me! Take a closer look...
01:48...at this!
01:51Volcanoes mostly form along the ridges of Earth's crustal plates,
01:55which allows lava to escape through those cracks.
01:58Also, pressure from magma can crack the crust, creating fissures,
02:02allowing lava to rise up through the crust and out onto the surface,
02:05in areas where the Earth's crust is thinner.
02:07Since volcanoes lay down layers of lava, areas of the crust can form pockets between these layers.
02:14Sometimes, magma rises up into the Earth's crust and gets stuck inside one of these pockets.
02:19Trapped magma melts the rock around these pockets, growing the size of the pocket so large
02:24that the layers of the crust above either collapse or crack apart.
02:28The pressure within the Earth erupts this 1,000 cubic kilometers of magma.
02:33These volcanoes are so destructive they can shoot volcanic materials that will travel for thousands of kilometers.
02:39If lava flows out for long periods of time and slowly over the surface, this will form a shield volcano.
02:46If the lava bursts out of these cracks in short spurts and cools quickly, it'll form the well-known cone
02:53volcano.
02:54If a volcano erupts both slow-flowing and quick bursts of cooling, it will form a shield cone shape known
03:00as a stratocone volcano.
03:02You know, being able to eat your science project right at home is why science is so wicked.
03:11I'm actually looking at it.
