Dimensional shift bomb

The dimensional shift bomb was a type of bomb which, as described by the Twelfth Doctor, sent particles to a different plane.

A dimensional shift bomb was left in a safety-deposit box in the Bank of Karabraxos to be used by a the Doctor, Clara, Psi, and Saibra, who had been sent to rob the bank. Planting it on the floor, the bomb detonated and blew a hole which allowed the team to reach the service corridors below. The particles were then quickly reconstituted, repairing the hole in the floor as the guards arrived. (TV: Time Heist)
