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.

Btw. I think there is a way to turn this into a digital number once again: Once all individual "buckets" have settled, you could put the fluid from each bucket onto a lever scale and put them at the corresponding distance to the center such that their pull on the lever corresponds to their number. So meaning: 8 _ _ _ 4 _ 2 1 | _ _ _ "measure" (maybe with a spring and a ruler). The number 8 corresponds to the fluid in the bucket which has the bit for 8 for example.

This is really cool. One thing I've always wanted to see somebody do is make an actual circuit that uses the hydrological equivalents to passive electrical components like textbooks always use to familiarize you with them. That is, use a narrow section of pipe or tubing in place of a resistor, use a flexible diaphragm that flexes back or forth as a capacitor. And use a weighted water wheel or turbine as an inductor. I've always wanted to see somebody try making something like an RLC circuit that oscillates at a specific frequency when energy is added in the form of voltage or current. OR in the case of the water circuit, by water pressure or flow. Which are the equivalents of voltage and current, respectively.

The leakiness/imperfect function of the gates honestly mimics real transistor behavior more closely. Because modern processors are running their clocks at such high speeds, the amount of time (nanoseconds) it takes for the voltage to rise or fall starts mattering a lot, so instead of reaching 0V for a logical 0, you might only hit 0.2V. by the time the output voltage is actually measured.

You can do an ancillary video about fluidics. The military actually built control systems with complex logic gates that operated in line with hydraulic fluid to perform ratio, multiplication and division operations that resulted in dynamic control surfaces that adjusted force output based upon input parameters like airspeed, inertial forces and pilot input. These were early attempts at making logic based control systems that would be immune to EMP in nuclear war. What they looked like was tall stacks of thin steel plates with channels cut in them, separated by gaskets, where the inputs and outputs where holes passing into adjacent plates on one side or the other. The whole thing was filled with hydraulic fluid at pressure, and the flow thru the various inputs controlled by valves and regulators, with the flow either resulting in greater or lesser hydraulic flow to the control surfaces.

While watching your video I actually came up with an idea of as to how to make a classic transistor using only water. Perhaps you could take a normal tube with a propeller in the middle which is supposed to act as a pump. The water from the first input comes directly into the center of the propeller, meaning that it won't be able to spin it much, but a second current of water comes tangent to another propeller that is coaxial with this one, meaning that both inputs have to have water flowing through them to have water at the output.

Informaticus (2003) had stuff like this. It's from a series of german educational point&click adventures, each focused on a different natural science. In Informaticus you were part of an archeological team who uncovers a lost civilization with knowledge on Logic/Computer Science. While I don't remember a water-powered computer, there was one puzzle that used crystal skulls as optic logic gates. Another puzzle had you program a robot to traverse a 2D labyrinth and there was also Conway's Game Of Life in it.

Great way to explain the logic. Just a note, in the full adder, the xor that doesn't belong to any of the half adders can be replaced with an or gate, in a real life situation you would probably want to have a circuit that is as simple as it needs to be. I get that using the syphons it's easier that way tho
