ypu will need
-a bolt and nut (nut does not need to fit bolt perfectly but must still touch all sides)
-two fake feathers (i only have one left so i will show you how to attach and at end put a picture of a better one that i made)
Step 1: Adding Washers Onto the Bolt
slide on another washer that is bigger than the first but the cant slide over.
slide small washer on as divider and then slide on another big one and repeat this part (you dont need to but i usually end with small divider to avoid a big washer sliding over the nut
Step 2: Blocking of the Washers
once you have as much room for the washers as you want but not to much room seal the nut on with super glue
if you are doing this inside do it over a paper towel to avoid spills onto the carpet or the floor wich usually results with mad parents
Step 3: Prepping the Feathers
Step 4: Adding the Feathers
Step 5: Finished
ps if you make the feather in twisty pattern at the attachment to the bolt the device will spin in mid air if you throw it way up and i havnot tried but it could make a cool trippy look if you attached colored streamers to the ends of the feathers.
