A bizarre and potentially tragic incident of mayonnaise bottles spilled on a highway in western Japan led to a series of vehicle accidents just after midnight on September 25th. According to Japanese news reports, boxes containing dozens of 500 gram bottles of mayonnaise were scattered over a 300 meter stretch of a two-lane bypass highway in Hyogo prefecture. Since mayonnaise is generally produced from a combination of eggs, vegetable oil, and vinegar, the spilled products essentially created a large oil slick on the roadway. Eight vehicles, starting with a motorcycle, and followed by several cars and trucks, crashed after skidding out in the mess.
