A red sharpie works real well.

If you want to change it to silver and gold, all you need is zinc, sodium chloride and fire.
You heat the zinc with the sodium chloride and stick the pennies in there. Once it's been a minute or so the color changes to silver. Take it out and stick the pennie over fire and eventually it turns into gold. (Something like that)
Coke or sprite will change the color of a penny.
Yes! In fact they change to a darker color or a greenish bluish color...
When ammonia cleans a penny, it reacts with the copper oxide layer on the penny's surface. This reaction removes the oxide layer and exposes the shiny copper underneath, causing the penny to appear brighter or even change color.
The penny is made of copper, which gives it its distinctive reddish-brown color, whereas other coins are made of different metals like nickel, zinc, and copper-plated zinc. Over time, the penny's color may change due to oxidation and wear.
It changes from the golden color back to a grey color.
Yes, it turns it gold,but don't keep it there too long or it will turn silver. :):)
The color of a penny is typically a copper color, which is a reddish-brown hue. However, over time and with wear, pennies may darken in color due to oxidation.

It is a physical change, because it does not change in substance. A penny, whether in its normal state or flattened, is still a penny. Similarly, if you drop a watermelon and it breaks apart, that is also considered to be a physical change because it is still a watermelon. Things are considered to be chemical changes when the substance changes into something new, and is commonly classified as irreversible. When an object rusts, it is considered to be a chemical change. Chemical changes are associated with a temperature change, or a color change or bubbling or something of the sort. Physical changes deal with physical changes in state, for example, ice melting, or in the example you provided, a penny being flattened.
