Cosmic Journeys: What an Astronaut's Camera Sees
An intimate tour... in 1080p... of Earth's most impressive landscapes...  as captured by astronauts with their digital cameras. Dr. Justin  Wilkinson from NASA's astronaut team describes the special places that  spacemen focus on whenever they get a moment.
Alkali metals in water, accurate!
Watch to the end for the best (Cesium!)! A wonderful representation of  the alkali metals and their accurate reactivity with water. unlike  brainiac, who did infact use explosives in their episode for rubidium  and cesium. Very worth a watch.
