you will need some hot glue/super glue, or possibly any glue, fuseless firecrackers, and a nerf bullet you are willing to take the original tip off.
Assembly: take the parts and glue the tube on the flat part of the plastic tip. glue the tube tip into the dart and put a fuseless firecracker in. This shouldnt break the dart or the tip when fired.
The author marked this model as their own original creation.
