I (the one building the spiral) made this domino brick experiment with my son Daniel (the one starting the chain reaction). It's not perfect, but we had lots of fun. In some funny way building the spiral was also very therapeutic. And I guess it felt cool to start the chain reaction too and watch all the bricks fall. I used Canon 5D Mk II to film and Premiere CS5 to edit. The spiral took about 30 minutes to build and 25 seconds to fall. We promise next video will be even cooler!
