Is this the thing that's finally going to get people to stop doing crazy gender reveal parties? Or will folks just double down?

A 56-year-old Iowa woman was killed at a gender reveal party in Knoxville on Saturday. (Knoxville is in Marion County, about 40 miles southeast of Des Moines)

The woman was identified as Pamela Kreimeyer, a 56-year old wife, mother and grandmother, in a news release Monday from the Marion County Sheriff's Office.

The news release states:

Members of the Kreimeyer family were experimenting with different types of explosive material on Friday and Saturday. They put a piece of wood on top of the gunpowder and some colored powder on top of that. The stand had a hole drilled in the side for a fuse.

Marion County Sheriff Jason Sandholt also released a statement saying:

This family got together for what they thought was going to be a happy event with no intent for anyone to get hurt. What ended up happening was that Pamela Kreimeyer, a wife, mother and grandmother, was killed by a piece of metal where a metal stand, gunpowder and colored powder were involved. This is a reminder that anytime someone mixes these things there is a high potential for serious injury or death; please do not take these unnecessary risks. My condolences go out to the family.
