Paste this into your console to play with velocity on a page that doesn't have it. It assumes jQuery exists already

Inject VelocityJS

(function() {
    var url = ["cdn.jsdelivr.net/velocity/1.1.0/velocity.min.js","cdn.jsdelivr.net/velocity/1.1.0/velocity.ui.min.js"];
    for(var i=0; i < url.length; i++){
      var v = document.createElement('script'); v.type = 'text/javascript'; v.async = true;
      v.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + url[i];
      var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(v, s);
    }
  })();
