Slippy Leaves
What just happened?
The leaf without Vaseline will wither and die first because the water from the leaf evaporates into the air.
Vaseline/petroleum jelly, helps to prevent the water "evaporating" (changing from a liquid to a vapor) from the leaf's pores. Hence, the leaf with Vaseline/petroleum jelly on both the top and the bottom sides, stays fresh the longest.
