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.

HIS FACE AT 6:42..... He GENUINELY is excited to see his creation start to work. That's the face of a man that wants to acquire endless cool pieces of knowledge just because he loves sharing it with others. I wish you were my teacher in school.

Clear, good explanations of phenomenon and of the underlying physical mechanism. Enthusiastic and a pleasure to view.

Your personality is lively and gives a good atmosphere.

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!

Good thinking with the 1/2 inch CPVC on the large setup! Great demonstration!

If I would have had the same demonstration in my classes, I would have chosen an other profession Well done. Loved the idea adding colloration to see the flow better.
