The working principle of an artificial waterfall in an aquarium using an aerator Video

Actually this is not underwater waterfall but white sand that falls from top to bottom continuously in the aquarium. If viewed from a distance it will look like a waterfall in the water.

The white sand is lifted by the air pressure from the aerator that rises to the top of the pipe. In a certain height water can be lifted up and carry sand from the bottom.

The sand that comes out from the top must come back down again by giving a sloping pedestal which is directed to the air source so that the sand can continue to come out from the top of the pipe along with the air coming out and going back to the bottom of the pipe.

Later, all equipment (aerators, pipes and plastic hoses) must be hidden with artificial aquarium cliffs or artificial stones which are deliberately made similar to make them look natural.

About the Site 🌐

This site provides links to random videos hosted at YouTube, with the emphasis on random. 🎥

Origins of the Idea 🌱

The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠

Challenges Faced 🤔

Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.

Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍

Creating Truly Random Links 🛠️

The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.
