Ice, Snow and Space

What experiments can be done with snow? why is snow white yet ice is clear? How can ice be made without refrigeration? And how do Jet engines work out in space? We tackle these questions in this week's show. We also find out about the Ares-V rocket being built by NASA, investigate why underarm hair hasn't been lost through evolution and reveal how someone's smell could reveal if they're your perfect match.
