Particle reversal

Particle Reversal is a method of moving objects. The Third Doctor tried to use a particle reversal to see inside a Time Lord message pod, but the device he created failed and exploded. In fact, if he had succeeded it would have pulled the entire universe inside the pod.

The Fourth Doctor used a modified technique to capture Lady Huntingdon. He used Iris Wildthyme's TARDIS' time rotor to program a particle reversal, pulling only Lady Huntingdon inside the message pod. (ST: Old Flames)(ST: Old Flames)
