The triangle is a tool we use in class for turning pages. It's a classroom job and a highly sought after job to boot. The person with the page turner job simply hits the triangle once when it is time to turn the page. This is a high skill job because not only do you have to know when to turn the page, but you have to have a knowledge of sound waves and how to let the triangle resonate throughout the room. When we reach the final page, the page turner gives the "call to dinner" sound. Now that's FUN! Don't tell anyone.
