According to Shot, an expert in the explosive case suggested that plastid was poured into the cavity of the bust and a fuse was inserted. A magnet was glued to the bottom of the figurine, which restrained the explosion activator in the form of a metal ball. When the magnet was removed, the ball rolled down to the moderator, after which the explosive device was remotely activated.
In another photo, the source showed what the magnet looks like.
"Trepova reported on her actions to the curator in correspondence on the social network", - Shot notes.
