Science Friday's (where every day is Science Friday!) Ira Flatow brings us this video of NASA astronauts testing out several different spacesuit prototypes. The "Spacesuit Ballet," produced by Katherine Wells specifically for the website, plays off of Neil Armstrong's description of his moon suit as "tough, reliable, and almost cuddly." "But that cuddly suit, made by the company Playtex," Science Friday notes, "had some stiff competition (literally) from rival rigid, metal designs."
