A High-Powered K'Nex crossbow that can reach a pretty long distance depending on how many rubber bands you put on it. Its made entirely out of K'Nex and Rubber Bands
Step 1: Make the rubber band holder.
This part is critical, so follow the instructions carefully
Step 2: Make the body of the crossbow
This piece is not so critical but is still needed
Step 3: Make the Trigger System
This part is a little tricky but is very important - without it the crossbow is hard to load and shoot
Step 4: Make the handle
This part is not really all that important, but it does make it easier to hold the crossbow
Step 5: Put the handle and Trigger System together
Click the Handle and trigger system together using the two white rods and the two yellow connectors
Step 6: Attatch the handle/trigger to the body
enter longer description for this step
Step 7: Attatch the body/trigger/handle to the bow
Put the the body/trigger/handle on the bow by connecting the yellow rods to the yellow connectors and the green rods to the yellow connectors.
Step 8: Add Rubber bands
Add the rubber bands between the two red connectors (I added sello-tape to improve performance)
Step 9: Add counter rubber bands
Add the counter rubber bands on the white and blue rods to make the trigger work - These rubber bands must overpower the other rubber bands for the trigger to work
Step 10: Add a Trigger
Add an orange piece to the trigger system to make it easier to use
Step 11: Bow Complete!
The bow is now complete, But don't go Yet, you need to make the bolts that it fires see the next step to make a bolt
Step 12: Make a bolt
Make this bolt (if you don't have the weird bit at the tip you can use a grey connector instead, or just don't have a tip)
Step 13: Fire The Crossbow
Pull back the Rubber bands and place them in the slot on the yellow connectors
Step 14: Put the bolt in
Put the bolt in the crossbow so that the orange connector on the bolt is sitting so the rubber bands are inside the end of it
Step 15: Pull the trigger!
Pull back the orange connector piece made in step 10! - but Be careful where you shoot it
