This new article is about methane gas released through one of Saturn's moon titans. I didn't know what a moon titan was so I clicked on the lick that took me to a Wikipedia article. I told me that is the largest of Saturn's moons that is much like earth. It contains stable liquid on its surface and is made of rock like earth. After a small probe took a picture of the moon titan the scientists came to the conclusion that hydrocarbon ethane instead of Methane must be a majority of the lake. This is because he liquids evaporate much more slowly than normal methane.

In this video he discusses gases pascal's principle and in-compressible fluids. He has some good demonstrations of these principles, such as shooting a paint can filled with water to demonstrate that water is (almost) in-compressible.
