Photographer Richard Heeks, from Exeter, used a fast shutter speed of 1/500th of a second and chose a perfect wind-free day so nothing would disturb his shoot, while his wife Sarah provided the all-important finger.
A bubble is made up of three layers - one thin layer of water sandwiched between two layers of soap molecules.
As Mrs Heeks's finger breaks the surface tension, the perfect sphere is replaced by a round mass of soapy droplets which dissolve into the air. And the bubble is gone.
