what is the size of the key rings?

I made several but only used 2 outers. What does the extra 2 outers do for it?

Maybe I miss understood. One of the pictures above shows 4 separate outer links in addition to the ones still attached to the inner links. Mine seem to work fine regardless.

I couldn't get mine to work... The links are too big... What size did you use...?

It's the chain for 1 - 3 speed bikes. As I understand it, chains for higher speed bikes have different sized links.

You probably have everything you need to make "the best fidget in the whole wide world"!! Mine is made of copper wire but you can also make it of keyrings!

Is there any way to take the bike chains apart without special tools?

Use a nail and hammer to punch out the pin in the chain or a nail punch what ever fits in the pin hole

I know a few kids who will each want one. Thanks.

Nifty! So how do you get your parts so bright? Even the new chain I bought for my bike is not shiny like yours, much less the used chain I'm using to make my fidget. Any advice would be greatly appreciated!

I degrease bike chains with 1:1 Simple Green and water. Drop the chain (or separated links) into a sealed jar with the solution, hand to someone who likes to fidget to agitate the jar for a while, then pull the parts out and rinse. An old chain will probably come cleaner, since the factory lube on a new chain is very resistant to removal.

I get things tidy when repairing bikes with "wet baby towel" or, for chains even better, the oily alternative product from the local drug store or pharmacy.

It is just a bike chain. Nickel plated for rust resistance. you can buy them any where.

I would love for you to make one for me and I will buy it. How much?

There are a lot of places online to buy them. They can cost upwards of $20. That is why I made this instructable. It is not fair to have a Mom or Dad pay $20 for something that cost under $2 to make. I have more design coming.

fidgetland.com has really nice ones for 5-7$

I love the idea but I don't have any bike chain that I can use laying around. Do you have any ideas of things I could use as a substitute?
