The results of YouTuber Atomic Shrimp's recent decision to establish his own window-sill pond ecosystem are strangely calming and fascinating. He started recording the ecosystem's growth after snatching up a jar of murky pond water, and in the process, he introduced his followers to some amazing creatures. He brought us along on his trip to observe the organisms growing in the water for three weeks.
These included a number of flatworms and the immortal freshwater creature known as hydra, which unwittingly turned into the film's unknowing star. As the top predators in the jar, the hydra engaged in combat with the flatworms using its stinging tentacles and slender green body. In fact, watching a hydra violently take down a flatworm during week two is truly amazing.
