Watch Astronaut Scott Kelly Play Ping Pong in Space With a Water Droplet

Jan 21, 2016

Astronaut Scott Kelly may be in space, but that isn't stopping him from having a bit of fun.

Want proof? On Thursday, Kelly tweeted a video of himself playing ping pong with a water ball aboard the International Space Station. "Try this, Mary Poppins!" Kelly said in the post, but there's no supercalifragilistic magic involved here. Instead, Kelly uses hydrophobic paddles that repel water to bounce a ball of water back and forth.

Kelly, who celebrated his 300th day in space on Thursday, is spending a year aboard the International Space Station. The ISS reached 15 years of occupancy in November.
