Woman tragically killed in 'gender reveal' party explosion

A gender reveal party has gone horribly wrong after a 56-year-old woman lost her life when a homemade device that was meant to discharge coloured powder instead exploded like a pipe bomb.

The Marion County Sheriff's office said Pamela Kreimeyer died instantly when debris struck her head on Saturday (local time) before flying another 132 metres and landing in a nearby field in rural Knoxville, Iowa.

Ms Kreimeyer was 14 metres from the device when it exploded.

Authorities said family members had been experimenting with explosives in the hopes of posting a colourful announcement on social media.

They welded a metal cylinder to a stand and packed it with gunpowder that they thought would send the coloured baby powder aloft, but authorities say tape covering the top of the cylinder caused it to detonate like a pipe bomb.

Law enforcement officials expressed condolences to the family and warned about the dangers of using explosive materials.

"This family got together for what they thought was going to be a happy event with no intent for anyone to get hurt," Sheriff Jason Sandholdt said in a statement.

"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 coloured powder were involved. This is a reminder that anytime someone mixes these things there is a high potential for serious injury or death." Sheriff Sandholdt added.

Gender reveals gone wrong

Using explosives to reveal a baby's gender is rare but a similar incident caused a major wildfire in Arizona in 2017 when an off-duty border patrol agent accidentally set off a blaze that burned 189 square kilometres of mostly forest service land.

The blaze forced about 200 people out of their homes and cost an estimated US$8 million in damage and firefighting expenses.

The agent, Dennis Dickey, fired a rifle at a homemade target that exploded, sending a blue substance into the air and started a grassfire that spread quickly.

Mr Dickey pleaded guilty in September 2018 to a federal misdemeanour charge of starting a fire without a permit.

He was sentenced the following month to five years of probation and fined.
