Water Task

[daydreamer0023]

Thanks for (unofficially) explaining! One more question if it's not too much to ask... Does the water have to be pure (i.e. distilled) or can it have dissolved ions in it (i.e. tapwater or saltwater)?

I'd suggest looking at this in 2 ways:
1. Would the average lay person (which is what the majority of SO event supervisors are) look at a given sample of tapwater or saltwater and when asked whether it was 'water' answer 'yes'?
2. Is there any reasonable way the average event supervisor would be able to determine at the event whether a given sample of 'water' was pure / distilled / tap / salt?

As always, this is not the place for official statements or clarifications.

Visibly the event supervisors would not be able to tell. However, they could test by simply using a voltmeter.

I think that the point chalker is trying to make is that whether its freshwater or salt water, it's still water. If salt water weren't considered water, what would we say the ocean was filled of?

For future reference, the FAQ here clarifies this, water must be pure on entry.

I believe bottled, tap, or distilled water should all be acceptable based upon feedback I received from the national event supervisor at the coaches clinic. They do not want any additives, including salt. Baseline dissolved solids in tap water will not be problematic since you can't even detect them without special meters or chemical kits.

So could we add water to a container that weighs it and presses a limit switch?

Per advice I received at the Centerville Coaches Clinic from the National ES, yes, this would satisfy the task description.

What does it mean by "closed container" in the rules? Can there be a small hole in the top of the container so that I can use a pipette to transfer water into the container?

Per the FAQ posted to soinc.org on 10/23/17: "The container must be closed but does not have to be air tight. When water is added to the container, any liquids and/or solids must stay within the closed container and no one can be physically exposed to them."

So the FAQS said you cant use salt water for the water task, would pouring the water into a container that has dry salt be against these rules? What do you all think?

That seems to be legal to me. So long as the water being poured is not saltwater, it should be fine. However, you're probably better off doing something more reliable, like this:

It is legal to pour the water into a container that has salt in it (according to the coaches clinic).
