NASA's YouTube page has ramped up efforts to give us Earthlings a glimpse into the scientific possibilities offered by a zero-gravitational environment.

In the space explorer's latest video, the U.S. astronaut Scott Kelly passes a drop of water, extended by a lack of gravitational pull, back-and-forth using two paddles.

Two laser etched polycarbonate paddles are coated with a Teflon layer, which produces a superhydrophobic surface that prevents water from being absorbed in "dynamic processes."

The scientists say that the smaller the droplet, the more force you can apply without breaking the seal.

Britain's Tim Peake has also taken to the video sharing platform to demonstrate the more mundane aspects of the life of an astronaut.

On Tuesday, following his thorough breakdown of how to brew a cup of coffee in space, Peake explains the finer points to using a toilet.
