Now I know what it’s called when a jet of water is smooth like a glass rod: laminar. Watch this video to learn more than you ever wanted about making a laminar jet of water from a normal one. Great for building your own fountains.

    That’s awesome! I knew that there was some special science behind these jets, but never knew what it was. Thanks!

  • Gav

    Very cool.

    this is a copyrighted method.

  • Brian

    Chrome, don’t be stupid. You can’t copyright a method.

    Also, who exactly are you saying has claimed copyright in this case?

  • zof

    omg its a copyrighted method everyone stop what they are doing right now, the law has been broken and someone is going to hang for making a PVC water fountain. Seriously since when has a copyright ever stopped someone from doing something like this on their own, copyrights are usually only enforced if you are making money from the copyrighted material.

    On that note I’m going to apply for a patent for a certain way of breathing then collect royalties the rest of my life, sometimes a system is just so broke you have to completely ignore it.

    It might be patented. But you aren’t going to get in trouble for making them for your own use.

  • Chris

    and you can even copy patents for your own use.

    Thank you for sharing this well-made video.

    One correction – about 2:00 it is suggested that two 1/4″ holes have the same area as one 1/2″ hole.  This is incorrect.  The area of a circle with radius r is = PI * r^2, where r is the radius.  So the area of one 1/2″ hole is actually TWICE the area of TWO 1/4″ holes, or FOUR TIMES the area of ONE 1/4″ hole.Hope this is helpful and maybe does not sound nasaly and annoying.  I would buy you a smoothie for your efforts.Ian Charnas
