This is an instructables for my friends who were afraid of using chopsticks...

These chopsticks allows you to practice secretly at home.

Besides this very practical reason it is fun to play with - and fun to make!

What is the secret of the two LED's? There is no electronics in my chopsticks!

Step 1: Materials

Chopsticks - i used the wooden chopsticks, for one time use.

Koper adhesive foil

Some electric wire

2 LED's

a 3V coin cell battery

Soldering station

Step 2: Making: Preparing Chopsticks

1. Preparing the chopstick

Seperate the chopsticks.

Cut thin strips of adhesive foil at the length of the chopstick.

Paste, glue, press the copper foil on the chopstick, from the tip to the top.

And for the tip of the chopstick: fold the copper around it.

Where you have copper foil over other copper foil: solder the connection between the two layers of copper.

Step 3: Making: Connecting LED's

2. LED's
The LED has two legs, long and shorter. I made the top of the chopstick fit the width between the legs, so the legs are at two sides. Cut some electric wire (as flexible as you can get it), at 5-10 cm length, 2 times. Solder the wires: short to long leg, and long to short leg. 3. You can make, crochet, knit a textile tube around the wires. Finished!

The explanation is basic - but funny: the LED is a diode and the LED's are opposite
in direction, so with the battery in either position, there will always be one LED having the right direction and not the other. See the circuit sketch.
