Inverted Bottle Dripper Aquarium Clip

cults3d

Drip acclimate new water into your small aquarium for cheap! Fits a 500 mL water bottle on 3.5mm rimless glass. The dripper To make the dripper: * 1x 500mL water bottle with screw cap * 1x straw, slightly taller than bottle * 5cm air tubing * silicone/waterproof glue Cut two holes in lid -- one for straw and one for air tubing Insert straw through lid hole so it will almost spans inner length of bottle Insert air tubing so 5mm inside inner lid Glue tube holes to be leakproof, careful not to block inside tubes Let set 24 hours Tie air tubing into a simple knot Fill bottle with water and screw on lid, then invert. Adjust tightness of air tube knot to control drip rate. Tip: use a stopwatch with 250mL to estimate total time to drip (about x2) -- at two drips per second, half a bottle dispensed in about 45 mins for me.
