Mildly Interesting

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

The Capillary Cup is a zero-gravity cup designed by NASA astronaut Donald Pettit on the International Space Station. The product is an open drinking cup designed to be used in a microgravity environment, developed from Pettit’s desire to drink water without a bag and straw in outer space.

Why not use a sippy cup like a toddler uses? They have these ones with little plastic membranes on top, that when you apply a bit of pressure open up and release the liquid at that point.

Release the liquid without gravity? I'm pretty sure any bottle design would need to be collapsible - basically becoming a bag at that point - to work in zero g, but maybe I misunderstand how these cups are supposed to work.

Just remember, when you’re using a straw, it’s not your suction that pulls liquid into your mouth, it’s the difference in the air pressure between the two that pushes it into your mouth.
