Step 1: Stuff You'll Need
-2 threaded hook things (IDK what they are called)
-3-4 inches of 3/4 pvc pipe
Step 2: Body
Take the two threaded hook things and slide (or hammer) them onto the pipe, like so...
One on the middle pipe section and the other on one of the other two
Then you can duct tape wrap the whole thing if you want to, just leave the ends of the pipe open, and the area between the hook and the pipe.
Step 3: Bands
Step 4: Finishing
Now take a shorter piece of cord, 1' will work as you can always trim it, tie a knot in it and then thread the other end through the hole of the hook and then down inside the pipe, take a pair of tweezers and pull it through the other section that is holding the band. And tie a knot there two, this is an optional step but it will keep the hooks from coming out.
Congrats, you are done, it should look something like this when you are done. You can hold it pretty much however you want to, I prefer to hold it with the middle section up in the air, like this
