Marshmallows are placed in a vacuum chamber and the air is removed. As the air is removed the pressure drops causing the air trapped in the marshmallows to expand. The trapped air expands to many the original volume and the marshmallows grows in size. This image is part of a series taken at different vacuum pressures.
