I encourage you to use whatever random crap you have to make this. I spent 5 minutes looking around for the supplies and you can improvise the stuff if necessary.
You're gonna need some tools my friend:
Step 1: Forage for Supplies
•some bar tape
•a flat metal bar
Do your best not to spend any money on this it would defeat the purpose of the project, but hey man not everyone lives with hoarders so I can see how it would sometimes be necessary to buy the stuff.
Step 2: Break the Chain
Step 3: Final Assembly
You're now done and can take off cogs left and right all of your friends will be like "oh my god dude where did you get that sweet chain whip" and you will put on a pair of shades and ride into the sunset. I've been there and it's pretty majestic.
