Step 1: Materials
Paintball Marker Barrel
The foam must be of a small cell size and cannot crumble. Anything less will disintegrate if put in a barrel.
Paracord is the best option for cording, because it is easily cleaned, tough, and forms large knots. In addition, Paracord is unlikely to cut the foam.
The scissors must be sharp, or else the foam will be curved on each cut. The knife will slice with ease if serrated, but serration is not necessary.
Step 2: Marking Foam for Cutting
Step 3: Cutting the Foam
Then, use a pair of scissors to snip at the corners of the cylinder until the barrel fits over it. The foam will look shaggy, but that is ok. Keep working your way down the cylinder until the barrel can slide over the whole thing.
Note: The fit should be snug, but if it is too snug, foam may rip in the barrel. Test the snake on your own marker before going into a match.
Step 4: Stabbing a Hole in the Foam
Gently press and twist the pencil down the length of the small cylinder. Be careful to never penetrate the side of the foam. Doing so will end the project.
When you are sure the pencil is past the end of the small cylinder, gently tease it out. Cut the end of the foam, and inspect the inside for damage.
Step 5: Adding Paracord
Gently puts Paracord through the hole in the foam until it clears the end. Tie a large knot at the end, and slide the foam to it. Then, tie a small knot right above the foam. This completes the snake.
