cream_ph/iStock(WASHINGTON) — Last week, residents of several New Hampshire towns were startled by a blast that rattled homes and could be heard for miles.The source: 80 pounds of Tannerite, an over-the-counter, highly explosive substance used for firearms practice that in this case was involved in a gender-reveal stunt at a quarry in Kingston.The man who bought and detonated the Tannerite in Tuesday’s blast turned himself in, and police said they’re determining whether he’ll face charges. In addition to the Tannerite, a popular method of gender reveals, police also found blue powder at the site of the blast, according to the New Hampshire Union Leader.Tannerite sells a gender-reveal “target” that contains just 1 pound of the explosive, along with pink or blue chalk powder.Police did not report any injuries in connection with the explosion, though have noted the dangers of potentially misusing Tannerite, such as sparking wildfires or damaging property.“If used improperly or irresponsibly, the consequences could be very serious,” Sgt. Jeffrey Dade of the New Hampshire State Police Bomb Squad told ABC Manchester affiliate WMUR-TV.The New Hampshire explosion is the latest gender-reveal event to make headlines. Others have had serious, even fatal, outcomes, turning celebrations into tragedies.In Mexico last month, two people died after a plane involved in a gender-reveal stunt crashed into water. In February, a 28-year-old New York man was killed when a device he was building for his baby’s gender-reveal party exploded, authorities said.In 2019, a soon-to-be grandmother died in Iowa when a gender-reveal device exploded and sent shrapnel flying. That same year, an airplane crashed in Texas after the pilot dumped about 350 gallons of pink water, authorities said. Both passengers survived, one suffering only minor injuries.Pyrotechnic gender reveals also have sparked massive, deadly wildfires.Last September, a firefighter died while battling a destructive wildfire in Southern California’s San Bernardino National Forest caused by a smoke-generating pyrotechnic device used during a gender-reveal photo shoot, authorities said.In 2017, an explosion set off at a gender-reveal party in Arizona sparked a fire that burned 47,000 acres in the Coronado National Forest and cost over $8 million in damages and in fighting the fire. The father-to-be, an off-duty U.S. Border Patrol agent who shot at a target packed with Tannerite, pleaded guilty in 2018 to federal charges stemming from the fire and was ordered to pay restitution, starting with a $100,000 initial payment and $500 monthly payments after that.Gender reveals, from dyed cakes and confetti-filled balloons to the more over-the-top, sometimes destructive stunts, are likely being fueled by several forces — a prime one being social media.“They’re these really increasingly Instagrammable-worthy things to be able to put on social media,” Rebecca Ortiz, an assistant professor in the S.I. Newhouse School of Public Communications at Syracuse University, told ABC News. “Gender-reveal parties are focused on a lot on color and ornate presentation, things that are almost perfectly translated into the social media space.”A gender-reveal post can be a form of “currency” to help build rapport and cache on social media, Kelli Matthews, a public relations instructor at the University of Oregon’s School of Journalism and Communication, told ABC News.“I think that’s really a phenomenon that’s unique to mid-to-younger millennials and Gen Z,” Matthews said. “That’s their currency. The sharing of information and the sharing of experiences is the currency of relationships.”Doing something “different” or “bigger” can help add to that currency and “cut through some of that noise so that we can really find our people and find our community and reinforce those bonds,” she said.Beyond chasing likes on social media, birthrate trends may also be partly responsible for the continued popularity — and over-the-top nature — of these parties, Ortiz posited.“While there’s plenty of people having children, people are having less children and waiting later to have children, so it’s a really special event and I think people are looking for ways to celebrate that, beyond just the traditional baby shower,” she said.In 2019, the number of births declined for the fifth straight year, according to the U.S. Centers for Disease Control and Prevention. From 2007 to 2013, the number of births also steadily declined.Copyright © 2021, ABC Audio. All rights reserved.
