(CNN) – A woman died after an explosion at a baby gender revelation party in Iowa, authorities say.
The 56-year-old woman, whose authorities have not given her name, was pronounced dead at the scene on Saturday in the city of Knoxville, according to a press release from the Marion County Sheriff's Office.
Subsequent research found that "a baby gender disclosure announcement resulted in an explosion," and the woman was hit by a piece of the waste that flew, according to the press release.RELATED
Gender revelation parties, which have grown in popularity in recent years, feature expectant parents who discover and announce their unborn baby's gender, often with guests watching and filming.

The revelation can be as simple as cutting a cake to reveal a color inside – blue for a boy, pink for a girl – to create great shows. At an Louisiana party, an expectant father stuck a melon in the jaws of a crocodile; When the crocodile chewed, the melon opened and splashed blue water everywhere, arousing applause in the crowd.
Another 2017 party in Arizona caused a forest fire that burned almost 19,000 hectares of land and caused more than $ 8 million in damage. In Australia, last July, a car that was used to emit blue smoke suddenly burst into flames, forcing the driver and guests to quickly leave the vehicle.
