Condensation trails – Mallaband-Brown

I joined a fun science page on Facebook this week. But soon realised that there were a lot of sceptics there. For everyone discussing a theory five seemed to be completely anti the facts! I should have laughed but I could not believe it! There were people who were anti everything.. I decided to leave the page.

I also posted to a page about clouds and again there was a discussion about chem trails (saying the condensation trails from aircraft have chemicals pumped out of them!). The trails are water vapour condensing around dust and ice particles in the air. My question to the commenter was to fact check his theory, he told me to check mine. What fun. I give up. Maybe science was taught differently in my childhood….

A friend posed the question, what comes out of airplane engines? Con or Chem trails? It’s a question I can’t resist answering, I’m hopefully telling you something you already know?

Condensation trails are what comes out of plane engines. Water vapour from the engines condenses out onto dust particles in the upper atmosphere. They cause the characteristic long thin trails up high in the sky. On the other hand chem trails were the US using crystals of silver iodide which is a harmless salt. It acted as nucleation point for water droplets and was washed out of the clouds it had been released into. They used it to make rain during droughts, I’m not sure if that is still the case.

There is a Kate Bush song about it which I’ve forgotten. We had to learn a few of them a few years ago I can’t remember which one.
