For July 4th, my parents and I had fun setting off fireworks in our yard. Somehow, it's legal in our city, and it has been for the last couple of years. However, we had the most fun with sparklers, because of the ability to do light painting with them.
My dad made a heart for my sister, who is studying abroad and thus can't celebrate American holidays here with us.
My mom and I did some light painting together. For those who watch Avatar: The Last Airbender/The Legend of Korra, this looks a bit like fire-bending.
The three of us went crazy, making all the shapes we could, in the time the shutter stayed open. This was the result.
