Guardian, 23 Apr 2021
A New Hampshire family’s gender reveal party was such a blast that it set off reports of an earthquake, and could be heard from across the state line, police said. The source of the blast was 80 pounds (36 kilograms) of Tannerite which is typically sold over the counter as a target for firearms practice, police said.
Local resident Sara Taglieri said "of all of the blast (she has) experienced, nothing was a loud" as the explosion on Tuesday evening.
