Wonder Woman notices that her invisible plane is covered in a strange green slime. Her friend Thor tells her to use a new window cleaner to get rid of the green slime. She decides to check this out by spraying (10 ml) with the new window cleaner to half the plane. She sprayed (10 ml) of water to the other half of the plane. After 3 days of “treatment” there was no green slime on the new window cleaner side and a little bit of green slime on the water side of the plane.
