Effervescence (Reversible)

By means of this spell, the caster can cause up to 1,000 cubic feet of liquid per caster level to bubble, froth, foam, and fizz like an agitated, carbonated soft drink. Thus, for each additional level of experience, the druid affects an additional 1,000 cubic feet. For example, at 2nd level, a druid would be able to effervesce 2,000 cubic feet of liquid, and at 3rd level, the amount would be 3,000 cubic feet of liquid. Small objects of up to 1-pound mass are drawn to the surface by this spell.

The reverse of this spell, calm, causes an effect similar to that of pouring oil on troubled waters: All liquids in the area of effect become calm – even rapids on a river or water in a boiling kettle.
