  • 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.

    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!

    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

      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.

      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 Před 4 lety +1

      @@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.
