how do you do this (i.e. have only the jar lit up and not the rest of the photo?)

That's not a question.

Post processing using masks and layers is one way to achieve such a result. As I don't see an example picture/link(because of my works filter policies on websites - not because of you not posting) I can't REALLY tell you. The other way is to use multiple lighitng sources and a dark background. Here is a link to a blog (not mine) on how to achieve some cool lighted water/creme colored drops effects. Perhaps you can apply a similar technique to jars. How To Shoot Liquid Flow Photographs

Looks like they simply put a speedlight in the top of the jar, though it's hard to say exactly without knowing what is in the jar, how dark the jar is, etc.

When your first post came up, it was only a link, no text, which is why I replied the way I did. ;-)

and how to do this effect?

I'm with fjrabon, it looks like the light source is coming from the top of the jar, which might explain why they cut the top of the jar off. But wouldn't a speedlight, even on low power, really blow out the jar? Meh, I have no idea.
Maybe it's just a small LED light?

OP: Honestly, I have no idea. And anything I tried to come up with would just be blowing smoke. Hopefully, one of the many, many folks here who could probably be of great help on this will be by directly and comment.

That one is just a powerful fan blowing her hair and dress. They placed her so that it barely touches the door and have good lighting in that room. Not really a hard "effect" as much as just having good preparation.

for the one with the jar, they used two lights above the jar, with a blue and green gel. or merged two shots, one with a speedlight with blue gell and one with green gel. actually, probly done that way now that I really think about it so you can get different water droplets with different colors.

so one shot blue, one shot green, one shot her holding empty jar.

merged masked all three together, and voila nifty picture.

I thought the droplets were painted on the inside...but what you say sounds more like it considering the kind of light in the jar...I wonder how long the person had to be standing there like that without moving the jar even a little bit...And still how come none of the hands or face is lit up at least a little. I am just curious if it is possible to do without much post processing so it really is a natural shot

Magic !!

Probly sat there for about 20 seconds for each shot...

I could be wrong, but I am guessing all the work was done in post processing, it would be the "easiest" way to achieve it. They don't even have to "hold" each jar, just take one shot of model dimly lit with an empty jar, then take the pics of the colored ones on a stand. When they merge them and mask them, the stand won't be a factor as they'll just be using the jar and masking it in over the empty one from the original shot.

I really, genuinely cannot wrap my brain around how you can be confused about such a basic principal, the jar is obviously brighter then it's surroundings. They were in a dark room, and they took a light and lit up the jar. What they used to light it is irrelevant.

Photoshop and masking? Yeah right.

 

[Ernicus]

the different colors explain the use of masking with different colored lights.

There are about 50 different ways to do this, so I doubt any of us is 100% right.
