Upcoming K'nex Challenge! Answered

Hey K’nexers,

Some of you may have noticed various Weekly Challenges that have been occurring over the last few months. These quick-fire challenges are aimed at challenging the community to complete a task based around a specific theme, like headphones or nachos, now it's your turn...

In previous contests the K'nex community has been ignored...nay, abandoned! It's time to show everyone how you guys roll!

I will be hosting 2 K’nex Challenges:
  1. K’nex Guns

  2. K’nex Projects (no rubber bands/guns)
    Ball machines / roller coasters / cranes / cars / armour, etc.
    No rubber bands or k'nex guns in any of the pictures or even mentioned in the description. Seriously.
You can enter both contests, but absolutely no guns allowed in the 'K'nex Projects' challenge.
Challenge yourself to meet either of these 2 contest criteria.

The projects that are going to win the top prizes are ones that are original, creative and have amazing pictures. Since making awesome K'nex projects takes time each of these Weekly Play Challenge will be 2 weeks, this forum posting is to give you guys a heads-up. Both contests start next week.

I want the K'nex crew to smash the previous Weekly Challenges, break 100+ projects and be the first to win top prize for these quick-fire challenges. Please wait until the contest launches to post your entries.

K'nex challenges start next week, good luck!
Both Challenges are now LIVE!
K'nex Challenge is now over.

Good luck!


For the Knex gun challenge, does it have to shoot? and, if I enter a project into the Knex gun challenge, will people still be able to view it on Instructables?

I've got an idea for the non-gun challenge, but it would use some rubber bands for cushioning. Would that be allowed?

No, there are no rubber bands permitted in the K'nex Projects Challenge, only the K'nex Guns Challenge.

Wait... if there are rubber bands, we post in the K'nex Guns Challenge?

Just a question, what if you made a gadget that requires a rubber band to work, such as a safe or lock? Would that be allowed in the project competition?

Nope, the challenge in this Weekly Challenge is to meet the criteria. In this case a k'nex project (which is not a gun) and contains no elastic bands whatsoever.

Good luck!

Just clearing it up. I thought that you banned elastics to make sure no-one bends the rules and posts a gun in the projects section. Which would have seemed kind of harsh to people who wanted to use elastics, but now I see.

the circular ball machine has practically become an instructables meme eh?

I problably didn't read the terms of use and such properly, but can you only enter if you live in America?

There is no location criteria for entry, prizes can only be shipped to continental North America.

Yes yes yes yes!

It's been some time ago since we had this. I'll get to work right away. Don't think I stand much of a chance against the other knexers though. ;-)

This is a really good idea. Thanks for making this challenge.

I want to see loads of entries from the entire K'nex community, someone has got to win top prize!

Can I enter something that I've already posted on here?

You may not get much this time around, because of The Jamalam's contest, and because not much new stuff is coming out. However you'd get enough for the projects section.

there's no reason why projects can't be submitted in both!

I'm putting an entry in your contest but I can't enter the second because I'm judging.

Do the projects have to be posted after the contest starts?

Yes, projects must be published after Challenge launches and before the deadline.

Totally copied me :P

Yeah, but he's getting paid for it. Staff wins.

You almost made me spill my water all over my desk, Thanks.

Hopefully a paper airplane-themed challenge like this comes soon. The paper airplane channel hasn't seen an official contest for years now. :/

Thank you for telling me! I hadn't seen it. I have now entered it though. :)

Im in. When and where do we submit entries?

I am sooo in this! SHIZZAM!

can you message me when the contest starts? thanks. KI

If you "follow" mikeasaurus, you'll get an email when he posts the announcement.

But seriously, could you postpone this until my challenge is over? I wouldn't want competition between competitions, if you know what I'm saying.

This Challenge will only add more projects to your contest.

Perhaps, but they are running in different formats, with different aims, and within the k'nex community this was meant to encourage innovation in numerous fields. What are the completion dates for your competition?
