Kingston Police responded to Torromeo Industries on Dorre Road to investigate the earth-shaking boom on April 20. Police found the blast was caused by an explosion of about 80 pounds of Tannerite, an over-the-counter “explosive target” that is used for firearms practice.

Because there was no property damage caused by the incident, police decided to only charge Anthony Spinelli of Kingston with disorder conduct “due to the fact that he caused public alarm.” Spinelli was the person in charge of the gender reveal party.

There were no reports of any injuries in this instance. But there have been a string of tragedies blamed on faulty gender-reveal devices in recent years, CBS News reported.
