minus-squarevillage604@adultswim.fanlinkfedilinkEnglisharrow-up3·8 days agoIt’s wrong. The stream twists because of the shape of the urethral opening.
minus-squarerants_unnecessarily@piefed.sociallinkfedilinkEnglisharrow-up1·8 days agoDoesn’t that count?
minus-squarevillage604@adultswim.fanlinkfedilinkEnglisharrow-up2·8 days agoNo, rifling is spiraling internal grooves. The urine stream twist happens because of the opening shape and water’s surface tension.
