For three weeks he took us along on his journey to see the organisms developing in the water.

This included several flatworms and hydra, an immortal freshwater organism that became the unknowing star of the videos.

Also fascinating is the hydra’s reproductive skills.

In the beginning, when the jar was filled with food, they simply cloned themselves through asexual reproduction.

New hydra appeared as buds on the parent before splitting off.

A small tadpole, possibly of a newt, had hatched.

These closed ecosystems are a great project for the whole family.

Placing Jar of Pond Water on Windowsill

YouTuber Atomic Shrimp scooped up some muddy pond water to create his own closed ecosystem.

Once the water cleared, organisms like flatworms and hydra were visible right away.

The hydra are especially fascinating for their predatory behavior and asexual production.

In the second week, there was even a possible freshwater shrimp sighting.

However, once a tadpole was discovered in the jar, the experiment came to a halt.

The closed environment wouldn’t be able to support its developing heart and limbs.

So Atomic Shrimp carefully returned the organisms back to the pond.

Watch all three weeks of the window sill pond experiment and see how the ecosystem develops.
