Why? Because they can, that's why....and it's fascinating and so darn cool!

If you are curious about the behavior of water in a near zero gravity environment, this video might just intrigue you. Three astronauts aboard the International Space Station decided to put a GoPro camera inside a floating ball of water.

Steve Swanson, Reid Wiseman, and Alexander Gerst recoded the video sometime during summer 2014 as part of Expedition 40.

Iflscience reports that:

In space, liquids naturally take on a spherical shape because they're in free fall. Therefore, gravity doesn't affect them like on Earth and rather it's surface tension that shapes them. Hydrogen bonding between water molecules naturally pulls them together, resulting in a spherical configuration that minimizes surface area.

The astronauts also filmed the experiment in 3D (You'll need 3D glasses to get the full effect)
