Lunar Elixir

When poured out, this silvery liquid rapidly expands and coats the surrounding area, creating a chalky white sheen across everything it touches. For the next 8 hours, gravity in a 20-foot-radius, 300-foot-high cylinder centered on the potion is like the moon's gravity. The jump distance for all creatures inside the cylinder is tripled, and falling damage taken inside the cylinder is halved.
