I created a great pair of nun-chucks out of some common PVC pipe, chain, and a little time. I found most of the materials around my Dad's shop and the rest I bought for very cheap at my local hardware store. These are great for karate practice, pretending you're a Ninja, or a good movie/theater prop.
Step 1: The Materials.
1--10 foot length of 3/4 inch PVC pipe. COST: $3.
1--12 inch piece of chain, any type will do. COST: 75 cents.
2--small screw eyes, you should be able to fit the tip of your pinkie through the hole. COST: 50 cents.
4--3/4 inch PVC end caps. COST: $2.
1--roll of black electrical tape. COST: $1.
1--can of PVC cement. COST: $4.
can(s) of spray paint. COST: ???
TOTAL (without optional)
Step 2: Tools.
Here is a list of some tools you might want.
A drill bit as big as the shaft of your screw eye but smaller than the threads.
Needle nose pliers.
A vice is a good thing to have but its okay if you don't have one.
Step 3: Construction!
Cut your pipe to the desired length and add the end caps. If you have PVC cement, now is the time to use it, follow the instructions on the can. Drill holes in the top end caps and screw in your screw eyes until they are snug. Now use your needle nose pliers and a little elbow grease to bend open a link on the chain, once open you may put it on the screw eye and close it around it with the pliers. Repeat to the other side. Now wrap your electrical tape around the pipe as much as you like, you may add more layers for a cushier feel and better hold. WARNING: DO NOT add weight to the inside of these!! Well, I suppose you could, but I wouldn't recommend it. If those things hit you in the leg and they're weighted, you'll go down like a dead horse.

Step 4: PLAY WITH THEM!!!!
Now you are finished, if you used PVC cement, allow it to dry before testing. If you expect to be using these at rapid speeds, I would suggest you move away from any breakable objects and stand on a flat, soft surface. Backyards work great, please don't take these on an airliner, the security guards WILL tackle you and yell, "Security, freeze!" into your face. And yes I know, they look awesome. Have fun and stay safe!
