ReCohesion Cannon
A ReCohesion Cannon was a type of weapon.
During a visit to the University of Edinburgh to meet Professor Bailey, Heather McCrimmon walked into a trap prepared for her by the Mozhtratta. The Mozhtratta took control of Heather's friends - Rob and Suze - and had them restrain her in front of a ReCohesion Cannon.
When Heather began being bombarded by the cannon, temporal echoes of her spread throughout the university. The Doctor saw one of these echoes and used his sonic screwdriver to find where Heather was. The Tenth Doctor found the room where Heather was and turned the cannon on the Mozhtratta, destroying it. However, time under the cannon had restructured her molecules to the point that she no longer had natural defences against vortex radiation. A single trip in the TARDIS would tear her apart.
