Add engineering, design, and creative appeal to your electrical circuits lesson. Blend design and technology while drawing a "liquid wire" circuit. Non Toxic water-soluble paint provides a new way to engage in electronics. Paint dries at room temperature and is suitable as a cold solder. Teach resistance, circuitry, polarity, or voltage in a fun, creative way. Works with electrical components, prototyping materials, PCBs, microcontrollers, e-textiles, and conductive thread. Includes application and storing instructions, but no lab activities. Use paint within 6 months of opening.
