Coustic Geyser

You conjure up a geyser consisting of hot acid. The geyser emerges in a 5-foot radius, 30 feet high cylinder centered on a point you choose within range. Creatures in the area have to succeed on a Strength saving throw or are flung 40 feet up into the air, before falling down again and gaining the prone condition. As the acid rains down all creatures in the initial area of the spell, and an additional 15 feet around it, take 20 (8d4) acid damage.

Huge creatures have advantage on the saving throw and gargantuan creatures automatically succeed. The geyser can also fling up objects with a weight up to 1000 pounds.
