Slightly different question.
Is the answer above true always? Or only true if A is filled beyond a certain volume?

It is definitely not always true. The outcome can be altered with slightly different starting conditions. From the Wiki article...
The answer is correct for the parameters I set forth in the OP.
Ha. I guessed the correct answer. The way I thought about it was that a balloon usually gets easier to inflate once you get past a certain point. That, and I figured it was a trick question and would be the least obvious answer. :-)
^^Excellent! If you watch the video, he gives what *may* be a clue when he inflates the larger balloon, taking obvious effort on the first breath, and a much easier time on the second exhale. Hard to tell if this was intentional or not.
You never know about those trick questions. Is he trying to smokescreen the obvious answer and make you pick the most bizarre choice, or is it really a tricker?
I speak jive.
(I guessed they'd equalize, too).
There was a pretty good clue at the beginning of this.
But not identical any more. The balloon has changed.

I chose #4 (air flows from smaller to larger balloon) upon first reading the question (before reading any of the--initially incorrect--responses of others). I confess that I remember seeing a demonstration of the effect when I was in high school physics class in 1953.

Personally, I believe you're the victim of a hoax.
The part of the video where he opens the valve is actually running backwards. Notice that he carefully ensured that his face was not visible during that portion. It would be difficult to hide that his speaking wouldn't match the audio.

Google "2 balloon experiment". This is a well-known phenomenon. I doubt that there could be so many people in on a hoax.
As far as the video running backwards, where do you see that? Try searching this on Youtube; are all those videos running backwards?

When the valve is opened between the two balloons...the larger balloon, due to its dominant nature, actually sucks the air out of the weaker smaller balloon...much the same way a cat (being the dominant creature) can suck the breath from a sleeping human (the weaker subservient creature)...it's just nature.
I actually expected them to balance out until both were approx. the same size...cool post

I can give you a real world example of the principles involved.
When repairing a bicycle tire you need to inflate the tube slightly to give it enough shape to get it into the tire to avoid a pinch flat. Care is required since the tube very definitely gets easier to inflate as you put more air into it. I use natural rubber tubes and it is very easy to blow one out, they will form a bulge, look like a cheap toy balloon and pop.
^^Good example! Thinking about it, it does sound right when I had a bicycle.

Yep, me too! Cool experiment.

Anyone who's made a poodle balloon animal should've been able to answer this correctly.
What? No one makes balloon animals???
