This is my first instructable so constructive criticism is welcome these nunchucks may be simple but if you get hit with them they hurt. So it's not my fault if you get hurt with them HAVE FUN!
Step 1: The Handles
Use 8 of the yellow rods to go all the way round two of the white circular connectors as shown below. And repeat. This makes your two handles.
Step 2: Handle Cores
Get the two remaining yellow rods and connect a grey connector to each end of the two rods and have two grey connectors by your side for the next step.
Step 3: Putting the Handles and Cores Together
Slip the two yellow rods through the centre of the handles and secure with a grey clip. As shown below.
Step 4: Finishing Off
Attach one end of the string to the grey clip on one of the handles, attach the other end of the string to a grey clip on the other handle.
