7:11 video
Vivian has two formulas in front of her. She knows they are both supposed to do the same thing. She takes the first one and grows into a nice Giantess and even saves a guy from a fire. Later she shrinks back and wants to be big again so she takes the other formula but this time she becomes an evil Giantess and many people.
