An empty paper towel or toilet paper roll.

Chartube is from Latin for paper, 'charta', and tube, 'tubus'.
Why do you always leave the chartube out in the bathroom? Just throw it out and put on a new toilet paper roll!

Two chartubes from wrapping paper make perfect play swords.

To make a sploof you need a chartube, dryer sheets, and a rubber band.
