Introduction: Knex Buckyball

Picture of Knex Buckyball

Everyone likes buckyballs, so what I did was make my a buckyball structure out of k'nex. It's fairly easy to build and can be built in about 15 minutes.

For this project you will need

- 60 full moon connectors
- 60 blue flexi rods
- 30 normal blue rods

150 pieces total.

Step 1: Making the Pentagons

Picture of Making the Pentagons

First thing you need to do is to make 12 pentagons using the full moon connectors and the blue flexi rods.

Step 2: Connecting the Pentagons

Now what you need to do is use the normal blue rods to connect the 12 pentagons.

Step 3: Adding the Connections

Picture of Adding the Connections

Attach the normal blue rods onto the full moon connectors as shown.

Step 4: Getting the Structure Together

3 more pentagons to be added. Place normal blue rods as shown.

Step 5: Almost Done

12 more blue rods and 3 more pentagons to go.

Step 6: All Done

And ready for cat use.

cool! I've never seen blue bendy rods: D

I've been trying to think how to turn most k'nex creations to ball machine elements. this could be a bowl the ball lands into that gets pulled down buy a motor operated... thing... then the ball gets launched by the bucky ball and gets reset by the motor operated puller-down-thing :)

Wow, just when I thought my OSSR would be the last gun featured for quite a while... but nice job.

Tom Buckey (author)DJ Radio2009-08-26

how do you get your ible featured??

DJ Radio (author)Tom Buckey2009-08-26

you need luck.

Tom Buckey (author)DJ Radio2009-08-27

so the admins just randomly picks ibles to be featured?

DJ Radio (author)Tom Buckey2009-08-27

no, I dont know how they select ibles.

Hiyadudez (author)DJ Radio2009-11-21

They select which ibles to feature by the grammar, pictures, clearness of the pictues, and last but not least, if it is actually good.

Im not saying your OSSR was not good, because it was, but like you said, its probably the crappy pictures.

Tom Buckey (author)DJ Radio2009-08-28

thanks anyways :)

They pick them by the quality of them.

Lowney (author)DJ Radio2009-10-25

 Your OSSR isn't featured, at least it doesn't have the little banner on it.

DJ Radio (author)Lowney2009-10-25

Well it did have one at a point, jerks unfeatured it.

Lowney (author)DJ Radio2009-10-25

 Bummer. Do you know why?

DJ Radio (author)Lowney2009-10-25

Most likely the crappy pictures.  

Whaleman (author)DJ Radio2009-08-07

But... this isn't a gun. So yours still is the last gun to be featured.

DJ Radio (author)Whaleman2009-08-07

whoops, I put "gun" in there by accident.

these are really known as buckministerfullerene domes. and we have a giant metal one out in the backyard.

DRADIS (author)2009-08-08

It's sad how many people probably have no idea what this is a model of, or of the mythological reference of the names of your cats. And where on earth did you get so many bendy rods?

RMConstruction (author)DRADIS2009-08-09

Theres a gerris wheel set with loads, and i have it XD !

Me too

Yep, but I never use them.

Hey... pretty cool

I_am_Canadian (author)2009-08-07

Nice! Featured! Good job. I only have two of those bendys though...

smilee (author)I_am_Canadian2009-08-07

I only have two too.

ergolicious (author)smilee2009-08-07

I got most of my flexi rods from the small K'nex Ferris Wheel set that was out a few years ago.

Me too

jedi_knight (author)smilee2009-08-07

really? wow I don't know how you get so few. but you end up with a ton when you have 2 knex ferries wheel sets.

Whaleman (author)jedi_knight2009-08-08

The mech sets from a long time ago had only one or two of them in there. I only had one of those sets, so I only have two of the bendies. They aren't very useful when you only have two of them, though.

smilee (author)Whaleman2009-08-08

I Bought two of them on for glitches barricade transformer!

jedi_knight (author)Whaleman2009-08-08

yeah well they aren't very useful when you have more of them then you do the normal blue rods.

bounty1012 (author)I_am_Canadian2009-08-07

Bartboy (author)2009-08-08

YAY! Somebody with feature powers has started looking at more knex! I bet it's kiteman.....


knexguy (author)2009-08-08

Very nice, I wonder if the member called buckminsterfullerene will notice this...

DJ Radio (author)knexguy2009-08-08

whos he?

knexguy (author)DJ Radio2009-08-08

No idea, but buckyball is a nickname for the form of carbon called buckminsterfullerenes.

gibzilla (author)2009-08-07

I took a philosophy course taught by Buckminster Fuller in 1970 at SIU. He was a pretty strange person. Brilliant but strange.

Killer~SafeCracker (author)2009-08-07

Wow, Your first instructable is featured. I wish mine were.

Hiyadudez (author)2009-08-07

Yeah, i agree with Oblivitus, however, i dont think many people have those bendy blue rods... Anyway... 5*

I have like 80.
