A plunger for clearing a clogged drain. The plunger includes a cup, a user-gripping handle, and a water-shielding cap. The cup is resiliently collapsible and has an uppermost wall with air-escaping throughbores that allow air trapped in the cup to escape therethrough when the cup is driven downwardly over the clogged drain so as to increase hydraulic efficiency of water in the clogged drain. The user-gripping handle extends upwardly from the cup. The water-shielding cap is attached to the user-gripping handle, just above the cup. The diameter of the water-shielding cap is such so as to allow the water-shielding cap to extend radially outwardly past the air-escaping throughbores so as to shield a user from the water escaping with the air when the cup is driven downwardly over the clogged drain.
