pennies don't rust, they're made of cooper, rust is iron-oxide (meaning it has iron and oxygen in it). But copper oxidises (tarnishes). so a liquid with a high oxygen content would work
"Speed of Corrosion: Comparing Rust Formation in Common Household Liquids"
Water and air in combination will rapidly cause iron to rust.
any liquid that had hydrogen, oxygen and is moist (of course it will be moist) to rust it need all the materials above can make pennies rust remember rusting only applies to iron items. to preserve pennies you can store them in oil
Vinegar is known to rust a penny the fastest due to its acidic nature, which accelerates the oxidation process on the coin's surface. Placing a penny in vinegar for a short period of time will result in visible signs of rust forming.
Most likely either Coke or Pepsi .
all acid solutions and most salt solutions and water in most formats
Because salt water has codium to make rust.
warm water will rust metal faster
