[00:00:00]What you're looking at may seem tiny, but inside this droplet an entire chemical reaction is happening in real time.

[00:00:10]The orange solution contains cobalt ions, while the other chemical provides hydroxide ions.

[00:00:16]The moment they touch, the ions instantly react and form a brand new compound called cobalt hydroxide.

[00:00:25]That blue line spreading through the droplet [music] is called a precipitation reaction.

[00:00:30]A precipitate forms [music] when dissolved ions combine into a solid that can no longer stay dissolved in the liquid.

[00:00:37]As the reaction spreads, [music] tiny cobalt hydroxide particles begin forming and scattering light, [music] creating that glowing blue appearance.

[00:00:46]At the microscopic level, billions of ions are colliding, [music] bonding, and reorganizing themselves almost instantly.

[00:00:54]This is chemistry happening molecule [music] by molecule inside a single drop of liquid.
