Water experiment in “zero gravity” environment will surely amaze you
An astronaut and chemist named Donald Roy Pettit aboard the International Space Station (ISS) experimented with water in a weightless environment during his off-duties as part of his Science Off the Sphere series.
In its episode thirteen, Pettit experimented with what he called Astro Puffs or a ball of water held in place by what looked like wire. He would then proceed to puff air on it using an empty syringe. The effect was that the air released through the syringe would create waves on the ball of water, propelling droplets away.
After that, he filled the syringe with water then squirted water through the ball of water. It, in turn, created a bubble inside the ball of water.

It was a really cool bit of experiment. After all, seeing a ball of water that seemed to be floating on air was a cool enough sight to see! Pettit also said that he would probably use the same water for his tea after.
