**Need Help Creating Water Feature / Fountain**

Hello! Thanks for allowing me to join the bulletin. I desperately plan to create a water fountain going from outside of my pool to the inside mainly for the look and sound (we live close to a highway). I've been torn between working on a DYI Laminar Flow Fountain or an arc appearance... and after seeing the videos below I feel I have made up my mind! I think I have everything I need from the PVC, spare pump and even the Waterproof Super Bright LED strip lights, but have a fairly critical obstacle to overcome. Some of the home made fountains look absolutely horrible! Some of them spray so non-uniformly and it makes it look very cheap. Does anyone know how I could recreate what's in the videos below? Should I look to insert some kind of nozzle in every hole, are they using a trick with a dremel, is it a certain hole size or pattern?? Any advice I can get would be very much appreciated. Thank you all for your time!
