Anti-plastic



Anti-plastic is a blue liquid used by the Doctor against the Nestene Consciousness.

The Doctor carried the liquid around in a vial in his pocket. He had originally planned to use the anti-plastic as a threat and a bargaining chip to make the Consciousness leave Earth, which the Consciousness refused to do.

While Rose Tyler rescued the Doctor, she knocked over the Auton holding the vial, who fell into the Consciousness and when it did so, the substance then reacted explosively with the Nestene Consciousness, which led a halt into the Auton invasion. (DW: Rose)
