That sounds counterintuitive. I have a leak-free water supply yet bet it wouldn't be Helium thight.

- tbrownaw 4y agoThere's a fun experiment where you can grease a kitchen strainer and if the holes are small enough it'll hold water because of the surface tension.

This is not true even at macro level.
- whatshisface 4y agoYour plumbing is leak-tight, but it's not water vapor-tight.
- fsckboy 4y agoplumbing is not water vapor tight?
- blatant303 4y agoPlumbing for gaz and water follow different norms and pursue different sealing strategy. This distinction is omnipresent in gasket and screw thread engineering.
- hgomersall 4y agoAt the molecular level, nobody cares about your intuition.
