About Water Tube

Getting Started

If you’ve ever poured out a cup of water, wrung out a towel, or sprayed something with a hose, you’ve observed how water acts here on Earth. However, what do you think happens when you wring out a wet towel on the International Space Station?

In this quick, easy activity, you can compare what happens when you wring out a towel soaked on water on Earth with what happens in space.
