IDK, if my 5-year-old asks "can you mix oil and water", I'll tell her, "sorta - if you just pour them into the same container and mix with a spoon, then no; if you add some stuff and know how, then yes - in fact, it's exactly what mayonnaise is".
That I had to be 35 before I learned that mayo is basically water mixed with oil, held together by eggs, it's an indication of what kind of education about the world we were getting...
At that point you're just changing the physical scenario the question was asking about, and answering about a different scenario entirely. You might as well respond to "can humans fly?" with "yes, with an airplane".
You can certainly reply like that to your 5yo, but it completely misses the point I was making. The video I linked to didn't suddenly modify the outcome being asked about. What it ended up with really was a mixture of plain oil and water, with no other ingredient ever being added to it.
