Where Is Liquid Nitrogen Used?

Liquid nitrogen is one of the most amazing substances on Earth. Its temperature is –321 °F (–196 °C), and that’s why it’s so useful in many areas of life. Let’s see where it’s used!

In Medicine

Liquid nitrogen helps doctors:

• remove warts and skin growths;

• store blood, cells, and embryos;

• preserve organs for transplants.

In Science

Scientists use it in laboratories:

• to instantly cool down different substances;

• to create superconductors;

• to test how strong materials are in extreme cold.

In Cooking

In molecular gastronomy, liquid nitrogen works like magic:

• ice cream made in just a few seconds;

• “smoky” desserts and drinks;

• flash-freezing foods to keep their taste and vitamins.

In Industry

Liquid nitrogen is also very useful in industry:

• cooling metals and plastics during processing;

• storing and transporting certain gases;

• creating a safe, oxygen-free environment to prevent explosions.

In Shows and Entertainment

Liquid nitrogen often appears in science and kids’ shows:

• for spectacular experiments with thick “smoke”;

• in theater and movies to make fog or icy effects.

Liquid nitrogen is not just “frozen water” — it’s a real helper in medicine, science, cooking, industry, and even entertainment.

Science works wonders!
