Watch the video above: Space station astronauts grow a water bubble in space.
TORONTO – What’s it like living in a bubble? Astronauts aboard the International Space Station gave us a view thanks to some pretty cool science.
While aboard the International Space Station, Alexander Gerst, Reid Wiseman and Steve Swanson explored water surface tension while in microgravity.

The astronauts were even able to put a GoPro camera in the water bubble making for some interesting views.
You can see surface tension in action here on Earth. When you wax your car, for example, the water molecules are more attracted to each other than the waxed surface of the car. It almost appears as though there is a skin keeping the water together.
There isn’t a skin, but rather surface tension. Surface tension is the property of the surface of a liquid that allows it to resist an external force.
