How Supercooled Liquid Water Causes Aircraft Icing: Demo Aviation Meteorology Ice & Chemistry

Here's a quick experiment to help you see how supercooled liquid water can cause aircraft icing! I actually received this experiment in a science kit from MEL Chemistry (melscience.com/US-en/chemistr... to see the set). This experiment uses a supercooled solution of sodium acetate and water, but the same principal happens with supercooled water suspended in clouds in the atmosphere.

Always remember that Laura, when you get right down to it, is just a pilot and a dispatcher. She is explaining facts from the source materials but may be incorrect or out of date. You should always follow your primary guidance (Aircraft manuals, government regulations, etc.) before listening to anything from this TH-cam channel.

Nice!
Bacteria n con.nuclei plays a part too..

Thank you for the experiment!

You are welcome! It was a fun one!

interesting. I wonder how icing and shockwaves are interacting.

[@orhananildemir4022]

but why? why when the aircraft hits the supercooledwater droplets, they become ice and forms on surfaces? what is the logic behind this process?

[@LauraLaster747]

There is a great video from Mythbusters about instant frozen beer that explains this somewhat. Basically the water molecules in very pure water can stay liquid below freezing, but when they are disturbed they instantly align and form ice. There is another video on TH-cam from the channel Veritasium where you can also see him do this with water (supercooling very pure water in the freezer and hitting the bottle to instantly freeze it!)
