Very carefully.
Household chemicals like Windex contain ammonia and other cleaning agents that can help remove dirt and grime from pennies. However, the primary ingredient in Windex is water, which can cause oxidation on pennies, leading to a dull appearance. To make pennies shine, a solution of vinegar and salt or lemon juice can be more effective due to the acidic nature of these substances, which can help remove tarnish and restore the shine to pennies.
no
well 180 pennies per pound so 180*4 would be 720 so yes 720 pennies for 4 pounds
To create a simple experiment with basic household items, you could fill a glass with water and place a coin in it to explore surface tension. Or, you could mix baking soda and vinegar in a bottle to observe a chemical reaction. Another idea is to create a homemade volcano using baking soda, vinegar, and a plastic bottle.

Acetic acid is the ingredient in vinegar that remove the oxides from pennies and makes them shiny again.
Cornflour, water and food dye of your colour!
Oh, dude, seriously? Alright, let me do the math for you. So, there are 100 pennies in a dollar, which means you'd need 100 times 500 pennies to make 500 dollars. That's like 50,000 pennies. So, if you've got a spare room to store all those pennies, go for it!
