A gender reveal explosion in the US shook homes three kilometres from the celebration and resulted in multiple calls to police. But while the noise frightened concerned neighbours no injuries were reported in the Iowa blast.
"They were there all day, celebrating," Waukee Fire Department Captain Tommie Tysdal told TODAY. "The boom was bigger than they anticipated and resulted in at least three phone calls... The property owner was very apologetic. He clearly did not mean for it to be that big and did not intend for us to be summoned."
"The kit was legal," Captain Tysdal said. "If it was used inside city limits, it would have been illegal, but because it was outside city limits, from a fire code perspective, it was totally legal."
The explosion occurred just a day after another Iowa gender reveal killed 56-year-old Pamela Kreimeyer. Ms Kreimeyer died after being struck in the head by a piece of debris from a homemade explosive device which was supposed to release coloured powder into the sky.
Last year, an off-duty US Border Patrol agent was fined $220,000 ($AU306,000) and sentenced to five years' probation after his gender-reveal party mishap sparked a 19,000 hectare wildfire.
The Tuscon, Arizona blaze, which 800 firefighters battled for a week in April 2017 and cost an estimated $8.2 million to extinguish, started when expectant father Dennis Dickey shot an explosive target also containing Tenorite.
In Australia, while we might steer clear of explosive devices, expectant parents have their own dangerous ways of revealing a baby's gender.
in 2018, NSW police announced that they were cracking down on "baby burnouts," a "reckless" trend they said was placing lives at risk.
Queensland Police followed suit, releasing footage of a car igniting after a burnout in April 2018. The 30-year-old driver was fined and disqualified from driving for six months.
And now, even the creator of the trend wants them cancelled.
"I've felt a lot of mixed feelings about my random contribution to the culture," Jenna Karvunidis wrote in a viral Facebook post about her 2008 reveal. "It just exploded into crazy after that. Literally - guns firing, forest fires, more emphasis on gender than has ever been necessary for a baby."
Asking, "Who cares what gender the baby is?", Ms Karvunidis conceded: "I did at the time because we didn't live in 2019 and didn't know what we know now - that assigning focus on gender at birth leaves out so much of their potential and talents that have nothing to do with what's between their legs."
And, in a significant plot twist, she noted: "The world's first gender-reveal party baby is a girl who wears suits!"
Carly Gieseler, an associate professor at the City University of New York's York College, who has studied the rise of gender-reveal parties says, "There's this huge pressure to publicise these once-private moments. You get that outside validation that what you did was unique, that it was extra special.
"It drives celebrations to the extreme because you're trying to do the thing that no one's done before."
