Step 3: Take the Back Off
Take the back of the pencil off with the Scissors.
Step 4: Take It All Out
Take all of the parts in the pencil out.
Step 5: Place the Band On
Place the rubber band on the end of the barrel.
Step 6: Tie a Band On
Tie the other rubber band by wrapping it on.
Step 7: Place the Pen Ink In
Now it's finished. Time to go shoot.
Step 8: Cock It Back
Pull the rubber band and the ink back with one hand while holding the barrel with another. Make sure the back of the pen ink is touching the rubber band.
Step 9: Let Go!
Let go and the rubber band will shoot the ink down the barrel and out toward the target. have fun making it :)
