Smoke & Joust

I shot some album art recently (worked with some talented folks, more on this as the project comes to life) and we had some leftovers from the shoot that I thought the kids would have fun playing with. Some 9' cardboard tubes from the seamless paper and a very robust smoke machine. I think I freaked out a few of the neighbors on the new block when smoke filled their yards, but we had a blast. And as a safe Dad, I made them wear their football helmets. What could go wrong?
