Speed of light

A bottle of the good stuff, bought last year from Brooklyn Superhero Supply in New York. But this isn't just any superhero supply store, it's a cunning disguise for the work space of 826NYC, a division of the American literacy nonprofit 826 National, founded by the author Dave Eggers. Anything bought from the shop (after correctly reciting the superhero oath of course) supports the charity. Such fun.
