Watch the video above for a nice description of what needs to be done to make a DIY laminar flow water fountain on the cheap. There are lots of different DIY designs and ideas from the community that are variations on this idea. See other ideas below.

 


 

 

Kanal von Magicmastera has made quite a few videos documenting his Laminar Flow Water Fountain build process. The installation and effects of his final design look great! He designed a great cutter mechanism which lets the stream get stopped and started smoothly with just a small disruption to the straight flow.

 


 

  has put together a video showing the steps he took to make his laminar flow fountain. The built looks very nice and should last a long time.  He has also added some RGB lighting to his stream, looks like his dog must love the new toy!

 


 

 

Zacharysc100 has made these two videos which demonstrate his DIY Laminar Flow Water Fountains construction method. He has put some serious thought into his design. Drinking straws like the others are his main weapon to make good flow.

 

 


 

 

Portojbc has made quite a few videos showing how his build works. The video above shows how his cutter works. He uses two solenoids to pull the cutter in and out of the water stream quickly. The results are quite good.

    There is a factual error in the first laminar flow video. The narrator states that a 1/2″ round hole has twice the area of a 1/4″ round hole. In fact, it has four times the area as the radius (diameter/2) is squared when calculating area.

    A=πr²
    A=3.1417(0.25″)²
    A=3.1417(0.0625 sq. in.)
    A=0.19635625 sq. in.

    A=πr²
    A=3.1417(0.125″)²
    A=3.1417(0.015625 sq. in.)
    A=0.0490890625 sq. in.

    I think they were talking about TWO 1/4″ holes vs one 1/2″ hole. In that case, they are correct, since it would be 2x the area you calculate above, which is half the area of the 1/2″ hole.
