Royal College of Art IDE Workshop: Liquid Switches
Turning LEDs on and off using Electric Paint
Materials To begin you will need:
1 x Electric Paint 50ml
Step 1 Introduction
These images show a series of liquid switches all constructed using Electric Paint and baby oil.
Because Electric Paint is water based, it will congeal to itself when put into oil. Baby oil works particularly well, plus its transparent so you can see what is happening.
In each of the prototypes, a ball of Electric Paint is closing the circuit between two electrodes.
