I believe there's a video on youtube with this, they used a whistle to signal when to stop and change teams. IIRC it was 2 minutes of exposure, followed by hour of cool off time or something like that.
But everytime I hear this story, I got to wonder who would pick up an object generating heat and not question why it's still hot hours later?
