Abstract A series of smart microscale electrolysis experiments were designed with fast reaction rate, clear phenomena and less pollution. Common materials such as chalk, test paper and cotton pad were used to absorb salt water as electrolysis cells, while iron nail, aluminum foil and pencil lead were used as electrodes. An ‘invisible’ and planar carbon electrode was made by 6B pencil drawing, and a beautiful chemical ‘cat’ was created by electrolysis on test paper. A sterilizer was designed using a plastic bottle by which hypochlorite could be produced in-situ through electrolysis of salt water. The content of active chlorine in produced hypochlorite disinfectant was 722 mg/L by iodimetry determination.
