"Uh. Nnnnno. I might be able to? But I haven't been interacting with anyone besides myself since, uh, here, so. It's not like I would know."

Sam deflates, just a little. “And it’s not like we can kill someone to try it on, yeah. …We could try it on an animal, Dream can bring animals back, but I don’t know if it works the same way.”

"I can do mad science with animals for the sake of bringing people back to life. What are the, um—the names floating over their heads, of the dead?"

“There’s only one dead person right now, as far as I know. It’d be jschlatt.”

"Okay. Well. I'll go looking for them and see if I can bring them back as proof of concept. Unless they're a person that really needs to stay dead? For some reason??"

“…I guess he doesn’t need to stay dead?” Sam doesn’t sound particularly enthusiastic about the idea, though. 

"... I'll ask other people before trying anything. And give a warning first."

“Sure. Quackity, maybe, Quackity knew him better than most people. I can give you a list of people who might know more?”

"Sure, that'd be great, thank you!"

“Quackity. Tubbo. Fundy. Maybe Wilbur, maybe Nihachu, maybe Ponk.”

"All right, I'll remember." She makes a note of them. In her head, because that's the best place to keep things, and it's not like she has memory problems. "Then I guess there's nothing in the way of finishing the tour, if you don't mind? I'm curious about what this world's like."

“Of course.” On the way back out of the egg room: “This is the spider XP farm, if you do end up needing XP for anything you can just hang out here killing spiders. —This is a water elevator, you can go up it without having to climb stairs, although I guess you can just teleport up. We should backtrack, we passed some things on the way here.”

“Just teleporting everywhere sounds boring, honestly. And I absolutely want to see what a water elevator does! Be right back.”

Accordingly, she’s going to go into it. She keeps track of her current coordinates to teleport back once she’s done.

Water elevator: you go in the water, you go up. Her Y coordinate, predictably, increases. 

She teleports back to where she was and then tries to figure out how it works. Does all water work like this? Or is something else going on?

Well, there aren't really any other nearby columns of water to test if all water works like this, though she could probably change that if she wanted to.

"Do you want me to explain or do you want to try to figure it out on your own?"

“Hmmm. Give me five minutes to figure it out and then explain if I don’t get it? All water doesn’t do this, right, I could test it by making water but that might make a mess, so.”

“Not all water does this, no.” 

She nods, then observes the water. There are… bubbles. Going up. Quite regularly, in fact. Is there something at the top or the bottom that’s causing those bubbles?

There’s nothing at the top. The block at the bottom, if she checks, is called “soul sand”; its tags are #soul_fire_base_blocks, #soul_speed_blocks, #wither_summon_base_blocks, and #mineable/shovel.

Getting to look at the bottom takes a lot of teleporting to fight the current sending her up, but she manages it! That’s neat. She pops back out, next to Awesamdude.

“Is it the soul sand at the bottom?” she asks.

“Yup. If you put a magma block at the bottom it pulls you down instead.”

“Really! That’s strange, I would have thought it’d be the opposite. But I suppose physics don’t work at all like I’m used to.”

“I’d be interested in talking about how you’re used to physics working sometime.”
