How to Make a Multi-Shot Nerf Gun

This is my first instructable so i'm going to do my best at showing you exactly what to do

Step 1: STEP: 1

Materials:
1 Marshmallow crossbow
12 nerf darts (anything but streamline darts)
1 rubber band
1 gatorade bottle cap

Step 2:

Now, take the rubber band and wrap it around all 12 nerf darts

Step 3:

Now jam the gatorade cap down the front until it wont go any further

Step 4:

finally take the bundled darts and jam them in front of the cap (if its hard to load squeeze the bottom of the bundle to flatten the bottom)
