SPEED FUNNEL V2

Speed Funnel – Version 2This is the second version of my original speed funnel design. Based on the feedback I received, I made several improvements—most notably, I replaced the fragile straw (which previously restricted water flow to 6 liters per minute) with external ridges. These ridges allow air to escape efficiently, preventing airlocks and enabling a much faster flow.The estimated flow rate now exceeds 15 liters per minute, though I couldn’t fully test the upper limit because I didn’t have a water source powerful enough to overwhelm the funnel.
