Vinegar contains acetic acid. The acid reacts with the outer layer of the penny, which is usually very dull because of oxidation, and removes that layer leaving a new, shiny layer from beneath.
When you put a penny in water, its density is greater than that of water, so the penny sinks. This is because the weight of the water displaced by the penny is less than the weight of the penny itself.
Salt water will rust a penny faster than vinegar because salt water is an electrolyte that enhances the electrical conductivity, accelerating the oxidation process on the surface of the penny.
If you put a penny in distilled water, the water will not react with the copper surface of the penny. However, over time, the penny may develop a greenish-blue patina due to oxidation from exposure to oxygen in the air. This process is slow in distilled water compared to other liquids like vinegar or saltwater.
Putting a penny under your tongue while taking your temperature with a thermometer can alter the temperature reading. The metal of the penny may interfere with the accuracy of the thermometer, leading to an incorrect reading. It is always best to follow the manufacturer's instructions for proper use of the thermometer.
The soda's acidity may cause some of the dirt and tarnish on the penny to dissolve, making the penny appear cleaner. However, the soda could also leave a sticky residue or discoloration on the penny due to the sugar content. It's not recommended to put coins in soda as the acidity can damage them over time.
Jesus appears

When you put a penny in fresh milk nothing will happen, but if you put it in curdled milk, the penny will become shiny.
You produce a lot of gas (CO2).
One penny is for my thoughts (thoughts normally kept to self), the second is for me to share my opinion outloud.
vinigar and baking soda can wash pennies or any coin. put it in a jar, and put a cup of each then shake, shake, shake! it should come out clean!

it turns stinnky and rots so than you put it into vingar ang it clean YAY YAY HOORAY
