Is Col. Chris Hadfield the geekist astronaut ever? Has there ever been an astronaut who sang and played guitar? Do all the astronauts enjoy themselves this much? I don’t know, but this is fantastic! I think the best part are his special effects, which are just shots of his normal everyday life. I’ve enjoyed a bunch of his videos, some with our 4-year-old daughter, but today’s (via Amal, thanks!) is a headexplody pop culture mashup. Thanks Col. Chris!
