Cam is dipping a grilled cheese sandwich into a bowl of tomato soup when he feels the summons. He goes ahead and grabs it. Doesn't even drop the sandwich.
"Enjoy! There is caffeine in the drink, by the way, don't overdo it unless you want to be awake late. Which way is east?"
"Oh, and if the sun goes down and you see a whizzing sparkly thing fall from the sky, those are safe and useful and you should collect it and bring it back. Fallen stars."
"I suppose you could use a net if you felt like it, but they're pretty small, so it would have to be a tight net." She gestures the size: not much bigger than a little cube. "They'll hit the ground and sit there until morning if you don't do anything to them, but if no one picks them up they disappear at sunrise."
He lets himself out.
The sun is low in the sky, but not yet down.
Flap flap flap. East east east. He'll make a floodlight when he gets there so he can see what he's doing.
Flying eyeballs look really gross. They're each bigger than a human head, and they are bloodshot and have trailing blood vessels and optic nerves that flutter around behind them as they attempt to slam themselves into Cam iris-first.
Dry ice, dry ice. Regular ice, in case that works; he doesn't know how good the air circulation is in these island environments and would not like to find out via Sable suffocating after he's been doing this regularly for a few years.
Architectural experiments!
It turns out he can just make blocks already placed in the invisible grid, floating. It's very disconcerting. He can also stand on these blocks. When he adds yet more weight to them, their staying power depends on what he makes them out of and they'll splinter and fall with their burdens if overweighted; he tries a bunch of things and finds that chlorophyte is more than good enough to hold an appropriate fraction of the ballpark mass of his usual house.
He makes a little floating house on top of chlorphyte blocks, as a test - it's more like a treehouse than anything - and goes inside it to attract flying eyeballs. After a while he comes out, kills all the eyeballs, and peers at the surface of the house. It's not damaged, even cosmetically; apparently eyeballs don't hit very hard. Still, he revises his house plan - solar panels so he doesn't have to dispose of infinite batteries powering his appliances, no black hole dependent disposal system, heavier curtains on the windows, a few soundproofing items (pity he can't put vacuum between the panes of glass on the windows, but he can make very sound-dampening curtains).
He encases the treehouse-thing in glass blocks with a Terraria-style glass door, to check back on later and see if it's gotten intolerably hot and/or on fire in there for future reference, but at least to start out he thinks he'll just float his house on chlorophyte without any blocks on the sides or roof.
He flies back.
The bottle of Mountain Dew has been flung across the room and is lying in a sad sticky puddle.
"You sure forgot to warn me about something. Is that what that was?"
"Remember the explanation of what dry ice is? If you put it in drinks, it makes bubbles. If you do something unwise, like shake a carbonated beverage, which I should have warned you not to do, it makes them way too fast."
"And not everybody likes carbonated beverages at all, I guess. I will clean it up since this is entirely my fault."
"The snacks went over better?" Cam makes a paper towel and wipes up the Moutain Dew. There is a little still in the bottle; he drinks it.
Cam finishes wiping up the Mountain Dew and then flings the paper towel out the door and sets it on hot enough fire that it's ashes before it hits the ground. "Oh, and it turns out dry ice is overkill, eyeballs explode just fine in regular ice. And they can't damage my floating house, and I can make unsupported blocks."
"Yeah. I'll probably make it in the morning when I can see what I'm doing even though I only adjusted my design a little bit from the house I have in Hell."
