"Penny had a theory about the toilet paper, saying she thought it was worse than jail," said Penny's mom, Lynn.
So Penny gathered samples from institutions all over St. Louis, including the police department, to flush out her point.
Then, she made a full poster board presentation and took it straight to the school principal.
Part of her presentation asked: "Is school toilet paper better than jail's?" The end result?
"It's the same and I can't believe I use this," said Penny.
And while she's stuck with the same scratchy TP, she's getting high praise for her grassroots campaign.
