A large explosion at a gender-reveal party rocked a New Hampshire town. Authorities in Kingston received a call around 7 p.m. on Tuesday about a large explosion at a Torromeo Industries quarry. When officers arrived, they found that it had been caused by 80 pounds of Tannerite, an explosive used in firearm practice. The blast was “earth-shaking,” and cracked the foundations of nearby homes, residents told WBTS. It’s unclear if any charges will be filed in connection with the incident.
