Some of the greatest science fair projects for middle school show up at the last second. I went to a science fair last year and I had looked around while the judges were taking their pre judging stroll. I didn’t see anything too different from what I’d always seen at these things but at the last minute I saw a student running to the back of the fair to give his team the final component of something they had covered up. When they unleashed it, it turned out to be the most magnificent display of fiber optic lights I’d ever seen!
