We all live or work with someone who still hasn’t mastered the difficult task of changing out an empty toilet paper roll for a new one. The next time you’re victimized by someone like this, send them the link to this video. It’s a father’s short instructional video on how you remove the old, empty roll and replace it with a new roll of toilet paper. As a bonus, he even shows us how to throw away the empty cardboard tube.

Of course, the days of empty tubes on toilet paper holders are coming to an end. Kimberly-Clark is now selling Scott Naturals Tube-Free toilet paper. It’s a roll that works like any other, except when you get to the last sheet it just rolls off. No cardboard tube.
