You will need:
1- soda bottle
2- presta valve (bike tube)
3- pla filament to connect the mouth piece to the presta valve (about 10 cm?)
4- lighter to melt together the pla cable to the mouth piece
1 to 2 breath under the water in a medium bottle.
Make sure all the parts are glued (melted together). If you do not glue everything together parts of the valve may end up inside your lung...
Instructions:
Cut the Presta valve tube the same circumference as the bottle cap. Make a hole in the center of the bottle cap to insert the Presta valve. Close the bottle.
Make sure your bottle is for pressurized drinks (pop).
Attach the mouthpiece to the printed valve. With a lighter melt a piece of PLA to attach the mouthpiece to the printed valve. Make sure the mouthpiece still moves.
Insert a piece of PLA filament in the valve and melt to the mouthpiece
Pump air in the bottle about 3-4 bars. screw the printed valve. Bla, Bla, Bla, you will figure it out...
