After all the adjustments, she is able to get water into her cup. She lifts up the cup and proudly states: "I poured some water from there into here." Without missing a beat, she lifts up the measuring cup to eye level and---like the scientist she is---asks: "How much water is there?"
As adults, we often overlook these types of accomplishments made by children. Of course, the water will flow into the bottle. Of course, you can pour water from there into here. The significance of these accomplishments has more to do with process of exploration rather than an actual outcome. The children set up their own challenges; they try out different procedures or operations; and they evaluate the results. No wonder some people think children embody the spirit of a true scientist.
P.S. If you are interested in other posts about the funnel and tube apparatus, there are two that explain different setups here and here. There is also another one that highlights other types of exploration at the apparatus here.
