Police in New Hampshire are investigating an explosion that shook homes in neighboring towns and was apparently part of a gender reveal party.

Kingston police said the explosion happened at about 7 p.m. Tuesday on the property of Torromeo Industries. Residents of Kingston and neighboring towns said they were startled by the blast.

"To have something like this occur outside normal business hours, and, of all of the blasts that we have experienced, nothing was as loud as we experienced on Tuesday night," said resident Sarah Taglieri.

The sound was captured on a home surveillance system miles away in Plaistow. For some, it knocked pictures off the wall. Others told police that cracks formed in their home's foundation.

Police said 80 pounds of a substance known as Tannerite exploded during a gender reveal party. The substance is an over-the-counter explosive target used for firearms practice.

The person who purchased and detonated the Tannerite is cooperating with investigators, police said.

"It comes with an oxidizer," said Sgt. Jeff Dade, of the New Hampshire State Police Bomb Squad. "The fuel is in a separate packet, and you mix it, and once mixed, you would place it somewhere safely out in a range where you would then shoot it."

Dade said Tannerite can be dangerous if not used properly.

"For example, if you are doing it near private property where the explosion could damage property, start a fire, wildfire something of that nature, there are statutes that pertain to all of that," he said. "If used improperly or irresponsibly, the consequences could be very serious."

Police said the investigation is ongoing, and charges are possible.
