Hebisuke — The Snake Whose Eyes Glow When You Bite Its Tail

We made a snake that lights up its eyes when it bites its own tail — meet ‘Hebisuke’.

This snake has a coin battery inside its mouth, and green LEDs for eyes.
The tail has electrodes made of conductive thread, and when they touch the battery, the circuit lights up the eyes.

Here's how it lights up.

I'd love for people to make lots of these and line them up.

Here's how to make one.
Give it a try!

Materials: felt, LED, coin battery, conductive thread
