Step 8: Attach Arms and "bowstring"
The bowstring is made by connecting about 6 rubber bands together on a string, and making a loop by tying the two ends together.
Step 9: Loading the Crossbow
This may be difficult at first, so point it downrange, so to speak. Two shots can be loaded side by side.
Step 10: Adjustable Power and Sharpened Ammo
Adjusting the power is done by moving the arms forward on their hinges, and locking them in place using the four extra pieces.
A pencil sharpener easily sharpens the tip of the ammo, but the blade dulls faster.
*Note: Caution is strongly suggested when using sharpened ammo. It is not recomended to use sharp ammo on your first try, or at anything living.
*Also note: If you didn't figure the first warning out already, it is suggested that you permanently dismantle the crossbow.
