Demonstration of how limestone is weathered

The ELI 'Weathering limestone – with my own breath!' is a classroom demonstration of how limestone is weathered. It involves blowing into neutral water to produce a weak acid. Powdered limestone is added to neutralise the acid, as a quick-acting laboratory example of how limestone is weathered in the
natural world.

This activity may be used in Geography or Science lessons.
