Chronodyne generator
From Tardis Wiki, the free Doctor Who reference
Chronodyne generators were devices planted around Coal Hill School by the Twelfth Doctor as a time mine to trap a Skovox Blitzer and send it billions of years into the future. However, Danny Pink disrupted the plan by moving the generators, so the Blitzer was only transported 2 days forward in time. (TV: The Caretaker)
