So the video about twisting a cup of water and pulling it up and it will retain the shape of the cup.. It doesn't seem real.
It could be real! Related to the penny experiment, the water in the cup is sticking to each other because of hydrogen bonds. I guess that's how it keeps its shape.
BUT! How is it possible that a tiny bubble of water collapses, yet a complete cup doesn't? Shouldn't gravity have prevented it from even forming? The tiny bubble from the penny was crushed, and obviously only a little bit of water was used. So why is it that the whole cup of water could keep its shape? It had tons more water than the penny did. I think gravity would be much to strong for the water to keep the cup's shape.
