It started to rain very heavily! By that time, Emma and Julia forgot that water could make them visible again, so they hurried to the closest shelter, their school. They ran inside the washrooms and got in a stall.
Emma: "Julia! The potion wore off! I can see you naked!"
Julia: "I can see you naked too! The water! It made us visible again!"
Emma and Julia were now naked in school, and people could see them! They ran out of the washroom, but everyone saw them and their nudes were taken.
When they got to Julia's house, they found a box that said "THIS POTION WILL LET YOU GO PLACES YOU HAVE NEVER BEEN BEFORE!"
