Wwyd if you were given a pocket dimension 3m cubed?
Rules:
*You can teleport into and out of it at will
*It has a couple of plug sockets and can connect to internet from the region you teleported in from
*You can take objects and people with you
*As already stated, it is (3m)^3 (3m*3m*3m). The walls are plain plaster with a light in the middle of the ceiling. The pocket dimension is topologically toroidal, so if there weren't walls and a ceiling/floor (which you can actually destroy) you would loop if you went more than 3m in any direction. Gravity, then, is artificial and can be altered to anywhere from 0 to 2g from a dial on the wall.
Edit: additional specifications
*You can only teleport out to where you teleported in from.
*Time proceeds at the same rate inside the pocket dimension
*There is an eject button for those inside to get out if something happens to you
First thing I'm gonna do is pop in there with a hammer and a crowbar and figure out how all this shit is wired up and what it's nailed to. Betcha there's a whole lot more space there than the realtor knew about.
I told you, if you knock through one wall, you'll be knocking through the opposite wall. As it's a toroidal space, they're the same wall. Same for the ceiling and floor.
I guess the power companies? But they won't notice such a small usage. Yes, that is also where mobile data/WiFi enters the pocket dimension, from the place where you teleported in.
The wires run ana and kata from the plug, and so all you see is a junction box with no holes, but even though you can't see any supports it barely wiggles when you tug on it
