Table Tennis With Water Drops Is Another Cool Thing That Happens In Space

By Chris Mills on at

There’s a long, long list of fun things to do in zero gravity, but when you spend an entire year in space, you probably get quite bored. That’s where space table tennis with water droplets and hydrophobic paddles comes in.


Commander Scott Kelly has spent nearly an entire year in space as part of an experiment on the long-term effects of zero gravity on the body. In has latest video, he shows how a pair of hydrophobic paddles can be used to guide a droplet of water around inside the International Space Station. Surface tension keeps the droplet of water together, while the hydrophobic paddles repel the water when it comes into contact.
