This is a instructable on "how to make a plastic bottle shuttlecock", it involves cutting the neck of the bottle off, and cutting the plastic (curvy top bit) into "feathers", It works relatively well for a DIY shuttlecock, but a bit heavy and has a dodgy flight pattern. This is a very simple instructable, but the cutting of the feathers is quite fiddly. There is a video of the final shuttlecock being served, this is on the final step! Good luck and experiment with it!
( vote for me on feb 2nd onwards, i want a solar bag! )
Step 1: What you need!
A plastic bottle - To form the shuttlecock from
Scalpel or Craft knife - To separate the neck and body, (scissors really don't work here)
Scissors (smaller the better) - To cut the feathers, (craft knife really doesn't work here)
Masking tape - To pad the shuttle's base
Fingers etc - to handle all above
