1 and 7. Knowing if things are empty might be marginally useful. Communicating with oysters seems fascinating. Oysters are similar to coral in that they are an important part of forming habits for fish. Being able to ask them what's troubling them could be useful for conservation efforts.

The person making this has never had gravel delivered for their driveway

2. Make bank by selling all that gravel.
3. I'm breaking into all sorts of places.

#2 is a farmer's wet dream.

7 is a power your character has in Fallout 4 and Starfield.

I would take 1 and 8. 1 because it'd be cool to talk to animals (even if it's just oysters) and 8 because maybe some oysters still speak Khitan.

Either 2 and 3 or 3 and 7.

Free gravel is fantastic, a ton of practical things to be done with it and is otherwise expensive.

Teleporting 7 inches away is enough to get you past many barriers and walls, that's not insignificant. This seems the coolest to me.

Being able to determine if a container is empty or not seems pretty cool as well although I can't think of a good example of how this would be useful.

The rest are hilarious.

2 and 3 are the obvious choices, however id pick 3 and 5. Here are the only interesting pills available.

(2) You can sell it

(3) that's enough to go through a wall

(5) a smart toaster has a circuit board that you could mcgyver into sending commands outside of itself, allowing ur toaster to be an entry point to computer telepathy.

(6) Would be funny to feed this one to a person who had just died and watch their color come back, really fuck with the autopsy

(9) Instantly cures any physical ailments preventing you from running/walking (unless we mean current albert einstein, in which case corpses cant move.)

3 and 5.

5 because it would even work on toasters that can do more than just toast, i.e. a toaster plus computer.

3 because the other pills don't sound useful. And it doesn't say how often I can use this teleportation. So I assume through repeated teleportation I'd be super fast. If it doesn't also teleport my cloths, I'd probably not use it too often though, apart from changing cloths (the 17.78 cm should be barely enough). It would also be interesting to fly using repeated teleportation. Though if my speed is not also reset through teleportation, I'd still fall, and landing would be dangerous. And if cloths and similar are not teleported with me, I also couldn't take a parachute or wings with me.

1 & 2 - as CEO of The Happy Oyster company and Gravel Unlimited lI’m absolutely smashing it financially, even with the terminal lamentations of a million misled oysters in my ears.

Step 1: cut off a limb Step 2: cry in pain for 9,5 hours Step 3: take pill #6

3 and 7. 3- you could get all those things that were just almost at your reach. Also, is it 7in of displacement or 7inches in front of where you are, like there’s a 7in wall you can go through it? 7- if you can’t see through it it means it’s full. That’s so freaking helpful!!!!imagine all those safe opening posts we could have avoided with this power.

If #8 also included being able to write the language as well, I'd definitely pick that. I could become famous and influential in linguistic circles and probably make good money off of it for a short while. Then I could use that money to fund a few projects I've wanted to do for a while, like making a modern Vib-Ribbon for PC.

As for the other pill, probably just #3 since none of the others really appeal to me in any way.

What type of molecules can be present inside the container for it to be considered "empty"?

3 and 7, without question.

3 and 7 no contest

2 and 7 I will trade gravel for everything I can.
