Every morning, I check on the water throughs that fill from the local pond. But something's wrong! A Deadly Nadder drank from it and now she's so feverish she couldn't even smell my hand. I think the water might be tainted.
We've got to find a way to clean the water before more dragons get sick. Can you ask Hiccup if he has any solutions?
Oh, that poor dragon! I think I have an idea. I was eating lunch with Gobber when I noticed something peculiar. Whenever Gobber stirred his yak noodle soup, the broth circled the bowl but all the kelp and noodles stayed in the middle.
He was separating materials in a liquid by churning or spinning in a process called centrifugation. I found out that bigger and denser materials get separated even faster. The effect looked so interesting that I sketched a schematic right then and there.
Aye, Hiccup showed me the schematic during the lunch and asked me to help. (I've always known that my yak soup was going to lead to big things.) I have a nice big container for stirring, a pipe for flowing water, and a spout for pouring.
Thank Odin for Hiccup's curiosity, Gobber's forethought - and his appetite!
Let's bring this all together. According to the schematic, the pipe needs to be attached to the top of the container. The dirty water will flow through this inlet pipe, drop down and churn around. We need to weld the inlet pipe to the container; can you ask [your dragon's name] to shoot it?
4- Shoot the bottom of the filter to weld the inlet pipe
The water is full of twigs, leaves and debris that we need to separate. When we churn the water, all the muck will gather at the center and leave the water fresh and clean on the outside!
Let's weld the container to the spout. [Your dragon's name] knows what to do; shoot the spout and weld it together!
5- Shoot the top of the container to attach the spout
It worked! That poor Dadly Nadder could really use a drink of clean water. Click on the sick dragon to give her the bucket of clean filtered water, please.
Astrid tells me that the wild Deadly Nadder is looking ten times better already! The filter watered is going to keep a lot of dragons healthy, all thanks to you.
