I Made A Water Computer And It Actually Works

Computers add numbers together using logic gates built out of transistors. But they don't have to be! They can be built out of greedy cup siphons instead! I used specially designed siphones to works as XOR and AND gates and chained them together so they add 4 digit binary numbers.

I love how an overflow error literally results in an overflow of water.

[carykh]

Man, seeing the siphons finally pass over the threshold, and start dumping out their contents... is so satisfying

[FinkPloyd]

It's weird seeing my same minecraft Redstone circuits made from water and actually understanding what's going on

[NetEnlade]

In middle school I forgot about finishing my science fair project, and seeing it was due on that day, I rushed to make an analog water computer to determine the weather. If you go outside and it is raining, then it is rain today. It was a very simple design.

I think this would work a lot better with mercury; it’s not as sticky.

"I have a water computer"
"Cool, do you mean water-cooled?"
"No"

Quick! Nobody subscribe!

Oh, I've never actually understood how logic gates work with binary addition before. I "learned" it in school, but never understood. This is such a clear explanation. Thank you!

Gamers: I have liquid cooled pc

Steve: I HAVE LIQUID PC

[MrStrez]

"have you tried turning it off and on again?"
"Yeah standby"
*tips the computer upside down*

[Fritzafella]

A memory leak 😂
I've watched a lot of your puns Matt bit I've never laughed this hard!

[bouncydachon]

“What are your specs?”

“I have a water computer”

“Water cooling?”

“Did i stutter?”

[GM-osbl]

The real question is: "Can it run Doom?"

[TheLimeLines]

That 'wet inside' on the thumbnail is amazing, there's some serious meme potential there

[VlogrBlogr]

13:45 this one scene just did more for me to understand computers and why they work, visually, than any other video on the internet. I get it now.

[daudmeer]

you should use hydrophobic coating inside of the containers and tubes so liquid dont stick inside of them and use distilled water or some other kind of fluid that can flow better

[samsibbens]

Bringing a brand new meaning to "integer overflow"

[samykamkar]

All of this boolean logic really makes me want to pee.

[PrebleStreetRecords]

This is so cool. My uncle, Bill Horton, did a ton of early research on fluidics and the fields use in computing, he would have loved to see this and how accessible it is to people.

"you've got a memory leak"

Laughed so hard at this that people came to see what the hell was going on XD
