Heather: "As the alchemist, I need to know about all types of science. One area is physical science. That's the study of physics and chemistry in nature. I'll tell you more about chemistry!
We use chemistry to figure out how and why the dragons breathe fire so differently. Go speak to each of the dragon trainers to see what they have learned about their dragons!"
1- Meet Astrid by the store at the school
Astrid: "Stormfly is a Deadly Nadder, and she's the prettiest and best dragon out there. She shoots pure magnesium, and it's the hottest fire of all the dragons!
If you ever ignite something you don't mean with a Nadder, don't throw water on it! It will only make it worse. You have to put it out with sand!"
2- Meet Hiccup
Hiccup: "Toothless is the only Night Fury we've ever seen. He shoots plasma blasts! We don't know much about it.
I read in a book that plasma is the fourth state of matter, where gas is heated to a super hot temperature and the individual particles become electrically charged! I don't think I know what that means yet.
Don't look directly at Toothless's plasma blast. If you want to look at it, wear protective eyewear and use a shield covered in leather!"
3- Meet Snotlout
Snotlout: "Hookfang is the strong, but he knows I'm the boss. He's my Monstrous Nightmare. He coats himself with his own saliva and sets himself on fire. Sometimes he does it when I'm riding him, but I know that must be by accident.
Oh, also, Hookfang spits fire when he coughs, sneezes, or laughs. Steer clear of Monstrous Nightmares when they're sick!"
4- Meet Fishlegs
Fishlegs: "Meatlug is my sweetie. She is the cutest! She's my very own Gronckle, and her skin is as hard as a rock. She also eats rocks, like granite, then shoots out lava.
If you ever need to cool a Gronckle's lava down, get out of the way and pour cold water on it. That's create a thin crust of earth and stop the flow."
5- Meet Ruffnut by her house in Berk
Ruffnut: "My brother and I ride on Barf and Belch, the greatest Hideous Zippleback out there! One of the heads creates gas and the other produces a spark. When they work together, watch out! It creates a massive explosion of fire!"
6- Meet Tuffnut by his house on Berk
Tuffnut: "We don't get burnt if we keep our heads apart. Oh, but here's a warning If you ever tell a Hideous Zippleback to fire, keep your head back! You might lose more than just your eyebrows!
Ruffnut and I speak from experience. That only happened to us twelve times so far."
Heather: "Without chemistry, we wouldn't be able to figure any of this out. It is an important tool for Vikings, and invaluable to learning about our dragon friends! Great job [Your Viking's Name]!"
