GlitterBug Potion is applied to students’ hands and rubbed in all over, including the wrist. It dries invisible.
When they wash their hands, the GlitterBug Potion will be removed with good handwashing technique. However, the Potion will still be present on any areas that are missed by the washing, and this will show up under GlitterBug UV light.
Commonly, the palms will be well cleaned, but the finger webbing, nail beds, wrists and edge of the hand will still show leftover Potion.
