Try this.

So it wouldn't be allowed to have smaller containers within your 3 liter container to demonstrate something like porosity?

And, uh...it's Station 4.

And uhh, to clarify, yes it's allowed.

Also, can you have water in your aquifer before station 4?
And can you bring a bottle to station 4 so that you can put water in and pour it from there?

[Skink]

Right, that was your question . Oh, you're clarifying it for the person who asked the question...

I don't see why not. Ask the supervisor. If they don't give it to you, then you can't have it. If they have it, then good for you.
Hmm...won't they provide that? The only thing that might trip you up is if they allow it but add that volume to the volume to your aquifer. As long as the two don't exceed 3.0L, you might wanna throw a bottle/whatever in with your supplies in case it is okay.

[Aquaman]

The supervisor should tell you that you can use a bottle. In case you are worried, use a beaker.

[TYG]

So even if the container was inside the other container, the combined volume can't exceed 3 liters? Like, say I have a container that is 2.9 liters and a smaller container that is .3 liters, and I put the smaller container in the bigger one, that wouldn't be allowed?

[Skink]

Good question, we dunno. 3.2L may even be allowed depending on who's supervising.
See, they allow stuff to stick out, and they allow smaller containers in the main aquifer. What they don't say is whether the supervisor will count that in the total volume. My guess is probably not so long as you aren't using it for demonstrating things in itself. But we don't know for sure.

I think I asked a similar question before, but just to clarify - if you do have those smaller containers within your aquifer and the total volume doesn't exceed 3.0 L, are you allowed to demonstrate a concept within the smaller containers and remove them from the aquifer so the judges can see?

I'm concerned about this because I don't know how to quantify porosity/permeability or show remediation without demonstrating in containers outside the main aquifer.

I think I asked a similar question before on March 26, but just to clarify - if you do have those smaller containers within your aquifer and the total volume doesn't exceed 3.0 L, are you allowed to demonstrate a concept within the smaller containers and remove them from the aquifer so the judges can see? Mmhmm, the clarification says you can have smaller containers within your aquifer. I can dig it up again if you'd like. I'm thinking it's implied they're for demonstration; otherwise, why would you have them in the first place?

I'm concerned about this because I don't know how to quantify porosity/permeability or show remediation without demonstrating in containers outside the main aquifer You should be okay...I've done it and did very well.. Porosity I can understand, but why do you need an external container for remediation?

I've addressed this one before...it probably depends on how strictly the supervisor adheres to the rules. If it were me, so long as the side containers don't exceed 3.0L total volume when added to your regular aquifer, I'm sure you're okay. However, I would try your hardest to demonstrate everything in the aquifer to be on the safe side. Go out of your way now to figure out how you'll demo everything within your aquifer just in case. For example, my team right now has a small container we use to show Artesian aquifer with, but we're prepared to modify or regular one if instructed to by the supervisor.
I wish there was a clarification about this. Here's the thing...

You may wish to bring additional smaller containers (drinking cups, beakers,
squeeze bottles, 35mm film canisters, salt shakers, etc) to put inside your larger
container, or use externally to store water or a ―mock‖ contaminant. This use of
additional containers is permitted.

Here they say you can have the external containers, but they never permit you to use them for demonstrating within themselves.

As far as, say, showing porosity in a pile of rocks your hands, it's the same deal. If they let you, go for it, but be ready to do it in the model if they require it. I don't see why it would hurt to ask beforehand if you're concerned (and they're not behind schedule).

The only way things could not go your way is if the supervisor interprets the rules in a funny way. I really think you'll be fine. They know how you'll demo porosity ahead of time, so they know you'll (if you plan on winning) have those extra containers.

The clarification in my old post actually answers TYG's question for sure--you can have the bottle.

Thanks a bunch, I'm just OCD about these things sometimes.

We're using activated charcoal to remove food coloring from water, so we need to place the water and charcoal in a plastic baggie and shake it for a while.

[Epicfail]

What exactly is activated charcoal?
