How To Make A Balloon Rocket - About.com Education
Here's how to make a balloon rocket using common household items and an explanation of what makes it move. This follows both Newton's Third Law of Motion ("for every action there is an equal and opposite reaction") and the law of conservation of momentum. ... Read Article

CHAPTER 9
In helium, a second electron can occupy the 1s shell, provided it has the opposite spin. The total spin angular momentum is therefore zero, as is the total orbital an-gular momentum. The term symbol is 1S, as it will be for all other atoms ... Read More

More About Rotons In Superfluid Helium 4
In reference1 it was argued that rotons in liquid helium 4 are not related to local vorticity in the superfluid (hence the name!). Instead, they approach, which unfortunately leads to the opposite conclusion: the meta-stable liquid phase should remain superfluid down to m =0. A normal ... Access Document
