It’s the season for baseballs, tennis balls, softballs, golf balls and especially an ice-cold snowball. Years ago, a Georgia company created “reef balls.” Eternal Reefs secures the ashes of the deceased, adds them to concrete and places them in artificial reefs. Owners of the company claim their “reef balls” help repair environmental damage by creating a perpetual reef. The balls are built to last 500 years, are equipped with holes to dissipate currents and generate a surface texture that encourages growth of coral and other marine life. A series of balls have been installed offshore, along the Gulf Coast, creating the Great Egg Reef. The cost of the human-remain balls runs from $1,000 to $5,000, with pet balls running about $500. Rest in Reef.
