A simple 30second blowdart and pipe that for sure will scare your friends off!!!

Step 1: Tools and Materials

Scissors
Beaten-up badminton shuttlecock - a New one will also do
Needles
Straw

Step 2: The Dart and the Blowpipe

It is obvious that the straw will be the blowpipe!
Nothing needs to be done, you can cut it shorter if you wish.

Remove one of the feathers from the shuttlecock. These are usually Goose feathers, If you have fake plastic ones, i feel sorry for you, they are lousy to play with
Just cut the 2 strips of strings holding the feathers and yank it out.
Its easy...

Then stuff the needle right in the front, not that hard either as it is hollow on the inside of the feather shaft.

Trim the feathers depending on your straw size. Trial and error determines what makes if fly best.

And guess what? stuff it in the straw and start shooting!

Step 3: Done!

You can manipulate the straw length and feather thickness to get a better flight!
There you go, a simple but scary weapon....
Who would want to get hit by a needle?

A good target will be cardboard or an old box!
I do not recommend real people.
