Before fancy-schmancy lightsabers, brave warriors fought many a duel with less elegant weaponry. Enter the Cardboard Tube Fighting League. The rules are simple:
1. Don’t break your tube.
2. No stabbing.
3. Not the face!
While the new sport might not make it to the next summer Olympics, you might find an upcoming cardboard tube battle at a park near you. So better get your tube and start practicing like young Luke Skywalker.
