Glitterbomb trigger device

From Tardis Wiki, the free Doctor Who reference

Yvonne Hartman carried a transmitter that she would later claim was a glitterbomb trigger device after Orr found it on Jack Harkness's person, capable of activating three glitterbombs which would scorch Cardiff. She had tricked him into taking it from her by saying it was a galactic lockpick. (AUDIO: Poker Face)
