Astronaut Scott Kelly marked Day 300 in space by playing ping pong with a drop of water and two hydrophobic paddles. The microgravity aboard the International Space Station causes the water droplet to form a sphere because of surface tension. The hydrophobic coating is necessary to prevent the water from adhering to the paddles.
