Just a pool, disguised as a pond, with a trampoline instead of a diving board.
I wrote a paper about these kinds of pools several years ago for a class when they were just prototypes. These pools have a natural filtration system that run based on the plants that are in the pool that give the water nutrients that allow it to not only be crystal clear, but you are also able to drink the water because it becomes so clean. And the best part is that once the initial filtration system is installed and calibrated, it maintains itself and eliminates the need for chlorine or constant maintenance like salt water pools.

In Slavic mythology, water nymphs (rusalki) are anthropomorphic creatures without fish tail who lived at the bottom of rivers. In the middle of the night, they would walk out to the bank and dance in meadows. If they saw handsome men, they would fascinate them with songs and dancing, but if there are no men nearby, they would gladly play and entertain each other.In some legends, their eyes shine like green fire, others describe them with extremely pale and translucent skin. Her hair is sometimes depicted as green or golden, and often perpetually wet. According to some legends, should the rusalka’s hair dry out, she will die.

Because of the weight of the ends of the forks, and how they’re distributed behind the penny (closer to the glass), the center of gravity of the whole system is actually shifted quite significantly. If I’m right, it would actually have to be right where the penny meets the glass. This mean, in a sense, all the “weight” of the system of the forks and penny is resting right on that point, rather than out in the air, so if you balance it, it’ll be stable on the glass.
