What is needed to create the universe?

It only takes two substances to create the universe in a drop of water.

If you add cobalt chloride and sodium hydroxide to a drop of water, a real mini galaxy appears.

Sodium hydroxide creates an alkaline environment where cobalt forms a blue precipitate that turns brown in the air.

Together with soluble cobalt complexes, the drop glows with pink, green, and purple hues.

Amazing: each droplet is unique due to its interaction with oxygen and humidity in the air.

This is a simple and clear example of chemical processes, demonstrating how complex structures can emerge from ordinary substances.
