OK, this is a bit off the beam, but still related. Great new infographic about toilet paper from visual.ly.
Visualizations and infographics are all now a part of digital literacy. This is a fun one to get started on. Try to do math in the new language. USA has about 300 million people, and uses 15 billion rolls a year. How many per person? And the circumference of the earth? That means each roll is how long? Science related questions focus on advantages and disadvantages of placing the roll so that it dispenses over or under the roll. Kind of like asking about use. Are you a buncher or folder? Things could get a little too personal.
