NASA astronaut sucks on balls to get his caffeine fix.

It is crucial to stay awake when on a mission in space, so drinking coffee is no brainer, except when you can’t actually drink it as you’re in zero gravity.

Air Force Colonel and ISS (international space station) crew member Jack Fischer came up with a genius idea to turn his coffee into balls, which can be dehydrated and easily transported. Now, whenever he needs a pick-me-up, he just sucks on some balls.
