Small knex gun thats awesome for its size. I know its a block but try before you critizise. Fires 10 - 20 feet.
Step 1: The Parts
These are the parts you will need:
5 Red connectors
4 Yellow connectors
2 Yellow rods
Red rods (ammo)
1 Elastic band (thicker ones tend to work better)
Step 2: Construct!
Place the yellow connectors on the yellow rod. (shown in pic 1)
Place the red connectors on the yellow rod. (shown in pic 2)
Continue doing this until you have something like pic 3
Step 3: Firing Mechanism
Place the green on the first red connector. (shown in pic 1)
Place the elastic band over the green. (Shown in pic 1)
Twist the elastic band around the green. (shown in pic 2)
Bring the elastic band around the sides. IMPORTANT- You MUST place the elastic band in the bottom gap of the yellow connectors or it won't work! (shown in pic 3)
The elastic band should cover the hole of the end yellow connector (Shown in pic 4)
Step 4: Fire!
Place a red rod in the hole of the first red connector. (shown in pic 1)
Push the red rod so it comes out of the end yellow connector and it should fit nicely into place with the eleactic band. Simply pull back to fire.
WARNING- This can be dangerous so DO NOT aim at a persons face.
