Lindsey Cutter's eighth grade science students put their lessons in physics to work making ball-bearing roller coasters, and the students and staff at Elizabeth Middle School voted on their favorites in several categories:

• Best Decorated
• Most Likely to Make Its Riders Lose Their Lunch
• Most Creative
• Most Realistic
• Most Likely to Seriously Injure or Unalive Its Riders
• Best of Show

The eighth-graders spent about a week-and-a-half devising, building, testing and decorating their coasters and, on Friday, set them up in the library for classes to stop by and take turns testing each before voting.
