Waves in Space

This comes courtesy of Luke S.:

This is an extremely cool video that demonstrates momentum and waves in space. It is almost like the physics land that we deal with so much in class. With an absence of a strong gravitational and friction force, most of the friction in these water droplet collisions is visibly conserved. It is also interesting to note the strength of the hydrogen bonds in keeping the water together.
