Revolutionary Knex Gun Competition 1 Answered

The Challenge: Make a firing knex weapon without elastic bands. Weapons that use elastics are allowed to be entered, but each instance of elastic use will reduce its chances of winning. A weapon that was created before the beginning of the contest will also decrease its chances of winning.

Rules: You may enter as many knex weapons as you like.

Criteria (in order of importance)
-Performance
-Innovation
-Appearance

Deadline: May 1st.

Judging: I'll pick the winner.

Rewards: The winner will receive my 5 star rating on their slideshow or instructable. The real prize, however, is the satisfaction of winning. The winning weapon will be announced in a forum shortly after May 1st.

Entering The Contest: Post a link on this forum to enter.

I will be posting a new contest near the beginning of each month until further notice.

I made this a few days ago, but I forgot to post it.

If basically a normal gun rain, with a 'car' on the rail. Attached to the 'car' is string that runs to the front of the gun and over some pulleys. Attached to the other end of the string is a big weight/counterweight. When released, it pulls the car forward (the bullet is infront of the car) and send the bullet flying out of the barrel, but the car stays in.

It shoots a blue rod 10-15 feet.

Nice! It's really original. Maybe you can try attaching something that's really heavy like dumbbells or sandbags and fire it by mounting it up high so that the weights still have space to drop. That would get much more range and greatly increase your chances of winning the competition.

I just changed the challenge a bit. You can use string, part tension, flexible rods, springs, magnets, motors, gear ratios, or anything else besides elastics to get a firing gun.

I doubt it'll win but can I enter my SYCAMORE gun?
https://www.instructables.com/community/Code-Name-SYCAMORE-Gun/
It uses a spring for the magazine even. It did use a band for the trigger but if you'd really fuss over that, I'd go change it into a spring or something. I suppose I could just make an entirely new gun that is better seeing how that thing was made in like 10 minutes.

You can enter, I just added this text to the challenge; "Weapons that use elastics are allowed to be entered, but each instance of elastic use will reduce its chances of winning." So removing the elastic on the trigger will improve your chances.

How about some provision so that people don't just enter a normal firing pin gun and say it just uses knex and tape?
