    <div id="source">
        <p>Drag the playing cards out of the stack and let go. Dragging them
          beyond the desk will throw them out of the stack. If you drag too
          little and let go, the cards will spring back into place. You can
          throw cards back into the stack after you have thrown them out.</p>

  // This method is called by hooking up the event
  // on the HTML element - see the template above
  onThrowOut(event: ThrowEvent) {
    console.log('Hook from the template', event.throwDirection);
