Whenever I take a walk I find something new

This past weekend was the 18th annual Science Festival (18ème fête de la science) at la Cité des sciences et de l’industrie, a sort of science museum/exhibition center. It was free this weekend, so this was a good opportunity (code for cheap) to feed my science habit.
