This guide will show you how to transform boring old pennies into shiny silvery wonders! The method of choice is, in this case, electrochemistry. Specifically, this Instructable will use electroplating to put the shine on your moolah. In other words, we will coat a normal penny in a thin layer of zinc metal and then shine it to a sparkle.
This is an alternative method for making silver pennies. Other methods include:
- Using sodium hydroxide (NaOH) and zinc metal to coat the penny
- Using zinc sulfate and zinc metal to place a zinc layer on top of the penny
- Other variants of electroplating
As for difficulty, this experiment is fairly easy and can be completed with stuff you've most likely got at home. After the overnight preparation, this experiment will take less than an hour. Enough talk, let's begin!
