Can you shoot marshmallows out of a paintball gun?

Anything that is designed to be loaded into a paintball marker that matches the bore size of the marker (can be from .50 to .68 caliber, and typically would be paintballs filled with water, other liquids safe for use in paintballs, or "reballs", paintball-sized rubber balls used for practice and or training). Use of any other spherical objects are not intended and may damage the mechanical components and may render it unsafe to operate.
