Not to be confused with Vortexpopper, a ranged weapon that also fires bubbles.

Effervescence is a craftable post-Moon Lord magic gun. It fires a spread of four purple bubbles that travel in a straight line before simultaneously erupting into three blue bubbles each; the blue bubbles travel in the same direction as the purple bubbles and linger before popping. The purple bubbles can pierce infinitely while the blue bubbles pop upon contacting an enemy and have slight homing properties; additionally, both types of bubbles will pop upon contact with tiles.

Its best modifier is Mythical.
