Yeah, I think they're like $4 or so for a single at Home Depot or Lowe's

How does the price compare to the Home Depot or Lowe's buckets?

You can't see the doctype tag between the quotes?

Yep, you're spot on

Well, it's not jet exhaust you're seeing, though.

I did acknowledge that, by the way. Jet fumes certainly contribute to global warming. I wasn't intending to imply they don't. Simply that it's not jet fumes you're seeing in contrails.

Ok, so what you're saying is I need to add bourbon to my nighttime routine?

The temperature difference is caused by the pressure difference. Airplanes have always caused pressure differentials. Jet engines just cause more pressure than wings and propellers do.

Well, it's not jet exhaust you're seeing, though. It's water vapor in air that's been compressed in a jet engine and then quickly decompressed out of the back, which causes the air to cool thus condensing the water vapor into droplets similar to those in a cloud.

See, I was guessing all star wars

 

"Impedance matching is one of the perpetual confusions for new electronics students, and for good reason: the idea that increasing the impedance of a circuit can lead to more power transmission is frighteningly unintuitive at first glance. Even once you understand this, designing a circuit with impedance matching is a tricky task, and it’s here that [Ralph Gable]’s introduction to impedance matching is helpful."
