On Saturday, a woman died at a gender reveal party - a celebration announcing whether expectant parents will be having a boy or girl. A piece of shrapnel from a homemade explosive struck Pamela Kreimeyer, 56, in the head and killed her instantly.
Members of the Kreimeyer family had experimented with different kinds of explosive material, the Marion County Sheriff's office said. They built a contraption to release pink or blue powder revealing the gender of the new baby, which they aimed to film for social media.
But instead, the device exploded like a pipe bomb, sending pieces of metal into the air that hit Ms Kreimeyer, who was standing 45 feet (14 metres) away. Some pieces of debris flew more than 100 yards.
Last year, a man shot a target so it would explode with either pink or blue powder, but sparked a 47,000 acre (19,020) wildfire in Arizona that raged for a week.
...
Even the woman credited with inventing gender reveal parties, Jenna Karvunidis, has spoken of her "mixed feelings" towards the phenomenon.
"Who cares what gender the baby is?" Ms Karvunidis posted on Facebook in July. "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."
