I take cold water in my tea to cool it down a bit - because I don't drink milk. I've noticed that every time I add the water it splashes very high. But the second time I add the water from exactly the same height, it doesn't splash to anywhere near as high. This always strikes me as a bit strange... Is there some stored energy which exists in undisturbed water and its surface tension, and is released upon the first adding of water, but not the second? Perhaps such an effect could be used to harvest extra energy from free standing water, maybe to build a perpetual motion machine extracting energy from the oceans? Or perhaps the water surface has an intricate fractal energy field, and is an example of a fifth force of nature? There's definitely new physics here.
