Japanese schools hold field-day events in spring and autumn, and large gymnastic formations are frequently performed at these events. Over 8,000 accidents related to these formations occur each year, one in four of which involves bone fractures. One factor behind these accidents is attempts at increasingly high human pyramids and towers. This paper calculates the structual loads involved in such human pyramids and demonstrates the dangers involved.
