A London skyscraper dubbed the Walkie-Talkie has been blamed for reflecting light which melted parts of a car parked on a nearby street. What happened?
It's like starting a fire with a parabolic mirror.
"Fundamentally it's reflection. If a building creates enough of a curve with a series of flat windows, which act like mirrors, the reflections all converge at one point, focusing and concentrating the light," says Chris Shepherd, from the Institute of Physics.
The half-finished 37-storey "Walkie Talkie"- nicknamed such because of its tapering rectangular design - is indeed a curvy building. Its design, which has also been compared to a brimming pint glass, has provoked controversy before.
It transpires the car, a Jaguar on Eastcheap in the City of London, was parked at just the spot where the focused light landed.
