This is an incredibly effective blow dart, its pretty fast to make and flies beautifully.
Step 1: Materials
All you need for this is a piece of a milk carton, a lighter, a nail, and something to mold it on, I found that a highlighter case makes a great dart for 3/4" pvc.
Step 2: Melt the Jug
You want to make the milk jug material go see through, slowly move the piece above the flame, dont let the flame touch it.
Step 3: Form the Tail
Push the see through area over the highlighter tube, be careful not to break the jug material.
Step 4: Cut Out the Tail.
Cut around the bottom of the mold.
Step 5: Insert the Nail
Push the nail through tail.
