Here's a couple of badass action shorts called Chalk Warfare in which two teams go to war with each other with weapons made out of chalk drawings. As you'll see in the films when the battle begins everyone starts drawing their weapons on the ground or on the walls. When they are finished they grab the weapons they've been drawing, and start blowing each other away. The videos were created by SoKrispyMedia. I thought these were really entertaining so I hope you enjoy them!
