Astronauts have all the fun.
Sure, they have to put up with highly restrictive living conditions, the crippling anxiety of social isolation and the constant threat of something going wrong - ending in a spacey, suffocating death - but they get a room with a view, awesome bragging rights and fun zero gravity experiments.
For evidence of the latter, NASA astronauts aboard the International Space Station have shown off a glorious 4K video of some simple tomfoolery involving water droplets and coloured dye. The video explains that they "dissolved an effervescent tablet in a floating ball of water, and captured images using a camera capable of recording four times the resolution of normal high-definition cameras".
They must be a riot at parties.
