The Siphon 

I loved this video. Very clear and the narration was simply fantastic. Well done to all involved.

my grandpa demonstrated siphon when i was a kid. i thought he was a god. lol.

What happens if the tube has different diameters at the ends?

Good color demonstration toward the end of the clip. Siphons were used extensively in recent history for irrigation of potatoes and other crops in arid agricultural areas. Might have too high of a water loss if water is scarce.

Thanks, im 55 and in my days school didnt teach this.

This is how to clean a fishtank :)

Amazin science-channel ever!!! El mejor canal de ciencias!!!

It's a good method to empty an aquarium.
