 Do you know someone who hangs their toilet paper the wrong way? Because the original patent from 1891 definitively proves there is a right way. See that right there? The inventor of the toilet paper roll intended us to put it facing out, obviously. But if that doesn't convince you, maybe germs will. Scientists say that if you want to reduce your exposure to bacteria, it's best to hang the TP over the holder. Because if it's hung the other way around, it's harder to reach. And fumbling for a few sheets could spread germs on your walls and on the toilet paper. Gross! So that's all the evidence you need to settle the great TP debate.
