Here's a short clip of fireworks over Disneyland which is about fourty seconds long or so. The castle itself is also lit up and they time the lighting on the castle itself to fit with the fireworks. When the fireworks are all white they turn off all the castle lights and you get a black castle silhouette against the fireworks. Presumably this is just a regular fireworks show and not a 4th of July show (and not from 2006 either). There are quite a few people in the crowd in front of the person taking the video too. Wonder what their recording restrictions are at these events.
Watch the full video clip below from the Disneyland firework show or click over and view it on the host site.
