Thank you, sir! That'd be really great, I need something portable to carry water around with me wherever I go....

In my world, we can manipulate the water in a--well, I know people have described it as weird magic before, even the great Sokka said so--so, sorta in a...magical way to heal?

[Korra's feeling awkward. How does she explain this? She tried to remember Sifu Katara's lectures.]

Okay, I use waterbending to have the water as this sorta, y'know, like a catalyst for redirecting energy paths through the body. And the human body is made up of a lot of water.
