Part 2/8:
To generate the necessary electrical current, Paul sets his power supply to around 10 volts, a voltage he has optimized through extensive experimentation (~50 previous attempts). He stresses the importance of consistent agitation and stirring throughout the process to promote even plating and prevent uneven buildup.
Introducing Silver Nitrate: The Key Chemical
A crucial part of the process involves adding silver nitrate to the water, which supplies the silver ions needed for deposition. Paul carefully measures a tiny amount of silver nitrate onto a popsicle stick, highlighting that only a minimal quantity is required—underscoring a common mistake among beginners who tend to overuse this chemical.
