This is the third video in my mini-series on plasma surface modification, water contact angle, and water itself.

We use water every day, so it feels ordinary. But scientifically, water is one of the most fascinating liquids there is.

In this video, I talk about:

• why water molecules are polar

• how hydrogen bonding gives water unusual behavior

• why water has such high surface tension

• why ice floats

• why pure water can be surprisingly valuable in research

• why water is such a powerful solvent

• why water is so useful in surface science

• and why, on very short time scales, water behaves in ways that are even stranger than most people realize

I also connect this back to plasma science and explain why water is not just a background liquid in the lab — it’s an active and fascinating participant in chemistry, physics, biology, and plasma processes.

This video wraps up the 3-part series:

1. Plasma surface modification

2. Water contact angle measurement

3. Water as a fascinating liquid
