Follow the pictures to string the crossbow.

Add extra rubberbands to the trigger if the bow rubberband is too strong.

The trigger rubberbands will counter act the bow rubberbands.

Dart

Rods
1 red
1 green
Connector
1 orange
1 black socket
1 grey

Other
Paper
Tape

Construct the rod then tape on the paper fletching at both ends and back. The fletching size depends on the power of the crossbow. Keep testing it until it is good.


Firing and Loading the Crossbow

Take the rubber band and wrap it around the two green connectors and put in the bolt. Press the trigger and shoot. Range depends on rubberbands and ammo. You can also shoot other ammo types like grey connectors.

This crossbow is only the basic form. You can make it smaller and also make it shoot two bolts at a time.

Problems,
The bolt keeps falling out:
Put some grippy tape in the trigger area.

The Rubber band keeps jamming into the gap between the yellow and green connectors at trigger:
Also use tape, but use smooth tape.

This is my first instructable, tell me if it is good!
