Impact sprinklers

Do you have an explanation for the "What's this weirdness" image? possible water on the lens or is it some strange electronical effect of the camera sensor, or ???

I don't get the image pun :(

David Letterman had an episode where they slowly rotated the whole screen over the whole hourlong episode. It was freaky how you kind of got used to it but then if you looked away from the TV for a second, your brain didn't adjust right away (because it was 12:15AM as well).

My spouse saw the screen part where the screen was rotating and just gave me a wtf face sort of thing because I guess it was just unexpected. It was priceless on both accounts - I laughed so much :) Thank you! I feel like it was missing that Simpson’s reference. You know the one. ;)

"Reciprocating water hammer"?

I'm very pleased with this type of video. Please continue finding and explaining those overlooked pieces of everyday technology!

Cameron Gunter

Pardon my ignorance, but what's wrong with "armature"?

:55 Dude!

I'm sticking with widdershins!!!

The weirdness - looks like some sort of post processing, such as video stabilization. If you haven't applied this yourself in post, maybe the camera you used did this for you. These sprinklers are (or were?) common in Israel. Being a water-poor country, though, we had had some innovation in the field. You should check out how a company called Netafim innovated in irrigation. They're pretty cool.

My grandpa always used the terms, clockwise and anti clockwise.

As a youth I found a cool trick with hand held water sprinklers was to adjust them into a 'lots of fine streams' mode which if done right can generate enough lift that the sprinkler will hover itself. Curiously the same water pressure in 'single steam' mode doesn't generate the same lift. Never quite figured it out but suspect it has something to do with surface area.

I was sure the outtakes would be of you getting wet! If you're interested, there's some fascinating tech in the water hammer effect. It's used by farmers to pump water up hills with no added energy source other than the water itself. Pure magic.

This is a video i had no idea i needed, thank you alec

nice vid, also xref This Ol' Tony's breakdown of push latch mechanisms recently posted...somewhat similar topic. https://www.youtube.com/watch?v=3_wPH904a_8

Nice thumbnail pun :D

Other places too... "impact (or impulse, or pulsating) sprinkler" is just used to differentiate it from other types of sprinkler, like the linear back-and-forth one he showed in the video.

I always wondered how the worked exactly. I had ideas on how they worked though. My favorite type of sprinkler are the tractor style that follow the hose around the yard.

Also, petition to add "electronicals" to the dictionary.

Good choice on the wrench as opposed to your hand.

I never seen those in Netherlands. A sprinkler is those things they put on ceilings in buildings. Sp if I understand correctly, they change direction so you can irrigate a part of a circle? With bonus of distributing water more evenly nearby and further away?

In Germany it's also just “Sprinkler“. Anyway, cool video!! Thanks a lot.

Ooohhh yesss! Looking foreward to watching this, these things were amongst the pieces if tech/mechanics I was most fascinated by as a kid but I never really bothered to find out how they work 😄

it wasn't an impact sprinkler, but i remember being fascinated (as a kid) by a type of sprinkler that uses the water's energy to turn gears which would move the sprinkler along the hose. That way you could lay out a fairly long or complex path to be sprinkled and it would cover everything, not just a circle or arc. A few seconds on google and now I know the proper name for this: "traveling lawn sprinkler".

That's interesting, I've never heard the name "impact sprinkler." They're just sprinklers to me.

Michael Dunn

They're definitely getting sillier, that's for sure

It feels like the videos have been getting more...passive-aggressive over the course of our current situation. Not complaining, just an observation. Also: armature.
