Water Demonstrations part two--Hero's Fountain // Homemade Science with Bruce Yeany

Hero's fountain is a device that lifts water to a higher height that it's origin in order to move to a lower position. This simple device was invented almost 2000 years ago and has several variations in making it but they all operate using the same concept. These devices will only run as long as there is water in the upper bottle. When the upper bottle drains out, it will stop flowing, usually drains in 2-4 minutes. The length of time is dependent on the diameter of the nozzle, a very small thin stream may last uptimes about 10 minutes.

[@1252PFC]

Thanks. Always love how you simplify the explanation.

[@Estabanwatersaz]

Never gets old of watching this video. Many thanks 🙏🏼

[@Tomyb15]

Your videos are always so interesting. They really inspire me to make these kinds of contraptions and experiment. As a way to pay this back, here's a little trick that you don't know about. When you have to empty a bottle full of water/liquid quickly, give it a nice swirl just before pouring. This way you create a vortex or whirlpool inside the bottle that lets air rush in at the same time that water comes out. Hope you at least find that interesting!

[@montyc1135]

Ciroluiro why would you assume that he DOESN’T know about that. Choose your words carefully. Btw, he DID swirl it.

[@Chepecafeteria]

3:35 wow it's so simple. I can't believe that I couldn't figure out how you were doing it!!

[@ArsenicFault]

I wonder if that oscillation in the large unit comes from the low volume of water in the catch basin? If that were more full, and more able to provide a constant stream of water, would the fountain go higher and be more consistent?

[@YeanyScience]

I was wondering what caused that myself, not sure what caused it. I want to go back and experiment with it some more.

[@abbasalkhakani5951]

Excellent job. God bless you

It runs till the upper bottle is empty.

[@mountain-roots]

Water tables and filtered water. Batteries and fountain. Imagine each bottle a tree. Now try to imagine the trees are just Stumps... The stumps are our mountains . Waterfalls our the fountains of life/youth. Charged water. If you like this idea i made videos as well.

that is right, water flow to the bottom bottle just create air pressure to middle bottle and push water fountain, no water flow circulation

[@JojonathanOliveira]

This is why I love physics, just looking at the device my head is brimming with questions, how big it would need to be in order to for the water to flow non stop for the whole day? Would it still work if the fountain part were bellow the reservoir? What would happen to the water flow if you change the girth of each pipe individually? And so many others.... I should build one myself =P

How long will the fountain run? Like will the pressure decrease after some time due to any external means.

[@jeffcook8501]

It should run non stop

[@PantherophisG]

It will run until the water reservoir bottle fills completely with air.

[@jeffcook8501]

@@PantherophisG that won't happen because the water coming out is going right back down to the bottom

[@PantherophisG]

@@jeffcook8501 But none of the water going into the bottom is then going back up. Eventually the full bottle will be empty, the empty bottle will be full, and there is no more pressure to run the system.

[@boostedandbagged9874]

I'm curious could this be used to build a water cooled PC?

[@HackedHawk]

you could but you will have to continually swap out the two jugs

[@PLASMATIER]

Not water as water conducts electric potential. The only thing utterly harmless to electronics would be mineral oil, and you would need significantly thicker inner diameter for the tubing. Still, yes.,The setup of a liquid cooled pc is feasible a and even commonplace for artists or people interested in higher computer power. Cool trick is having a fish tank of mineral oil sealed airtight in a fish tank to give the illusion a sunken computer tower.

[@kelsroom2]

how long is the water circulation?

this will work until only first container water finishes .. how it will be continious fountain

[@timhallas4275]

It isn't continuous. It stops when the bottle is empty.

[@seanregehr4921]

It is continuous in the sense it continuously flows without any external forces. Place it outdoors and it will operate will almost no human effort as rain will refill any lost water from evaporation etc. Even in colder climates the water can free and as soon as it melts it will start back up as long the water level is sufficient.

[@timhallas4275]

@@seanregehr4921 Wrong. The "external force" is gravity. The water had to be lifted to the upper container in order for this action to begin. That is applied potential energy.. Once the upper container is empty, there is no longer potential energy available. The idea that rain filling the upper container is adding energy. The point is, this is no more perpetual motion than is the water cycle .... evaporation...condensation...precipitation. It requires energy from the sun to work.

[@seanregehr4921]

@@timhallas4275 - I guess you missed the explanation of how this works. Pressure raises the water and is the auto-balancing mechanism. All that is needed to maintain this function is the correct water level. The water cycle is perpetual motion.
