Scott Kelly has been on the International Space Station (ISS) for over 300 days straight, nearing the end of his One-Year Mission.

As a little celebration of his extensive residency onboard the ISS, NASA has released a video of Kelly playing around with some hydrophobic, or water-repelling, ping pong paddles and a ball of water in microgravity. The video is filmed in 4K quality, so make sure you turn up those YouTube settings under the cog on the right of the player.
