This woman totally seems like she has harnessed the power of a black hole and can suck up all the light and everything around her. But it's just a nice little camera trick showing swinging burning steel wool in reverse. The light flies to her as she twists and turn but in reality, it's just being flung away. Still nice though!
All necessary safety precautions where taken to prevent the risk of a fire. We only shot after heavy rain (Cumbria gets alot of rain) and had a team of people standing by off camera. The steel wool we used burns out really quickly which made the risk of a fire extremely minimal.
