The man was given the pineapple-style grenade by a neighbor, who used the explosive as a bookend, deputies said.
When deputies arrived in the DeLand neighborhood, they found the man, who told them he had pulled the pin on the grenade, put the pin back and placed the grenade outside.
The man told deputies his neighbor had a second grenade.
That woman told Local 6 the grenades belonged to her deceased husband, who fought in World War II, and were used as bookends for several years.
The explosions left a 2-foot crater in the ground. Link -via Arbroath
