She just giggled at the idea and shook her head, "Yea I can do that, and I think I have the stuff in the basement I  made it my own little personal lab of sorts". She giggled and took a deep breath suddenly shaking her head, "Although it would be difficult to do so, the panties of the girls are kinda.... hidden you know and they are mostly on their rooms or near the house, it has to be stolen by night and one by one". She shrugged realizing that she perhaps ruined the entire idea of the prank. "I mean it sounds like a awesome idea however there is too much against us on that one"
