If you slowly move the cardboard the coin on top will move with the cardboard. Law of Inertia. There is not enough force to drop the coin into the water.
te coin will just stayed on the card board..
it is because the view we are seeing the coin is from rarer to denser that is from air to water so the refractive index differs so the view we so the coin at the bottom of the cointer appears to be raised
The structure of the feather makes it catch the air and fall more slowly than the coin. Refer to the related link for the Apollo 15 mission to the moon, which has no atmosphere, in which an astronaut drops a hammer and a feather at the same time.
Friction is a sticky force that appears when 2 objects rub against each other. If you push or pull slowly friction helps pull or push the tower along with the bottom coin. If you push or pull quickly, the coins still rub, but the friction force doesn't have time to get the stack moving. So the coin shoots out without pulling the tower with it.
When I slowly pulled the cardboard, the coin placed on top of the cardboard remained at rest but was dragged along with cardboard. Explanation: That is because, the coin was dragged by the force in the surface of the cardboard called friction.

The coin fell into the slot, May pulled the plunger and the apple fell out of the vending machine. Eric tossed a coin into the fare box, so he could ride the bus. The Euro can be called the 'coin of the realm' in most of Europe.
I got an old shoe box and put pieces of cardboard in to separate the the dollars and change. That's an easy way to do it.
DO NOT CLEN WITH LIQUID!!!! I recommend you take a tissue place it over a coin and very carefully and slowly scrape the rusted areas.{Be careful not to scrape the surface of the coin or you will diminish its value}
Before beginning the trick, hide a coin in your left palm. In front of your audience, put an identical coin in your right palm. Now, with both hands as fists, spin them around or knock them together. This may be done slowly to emphasize that the coin hasn't moved. Have the kids guess which hand the coin is in. No matter which hand they guess, the coin will be in the other hand!

US mint sets 1958 and before are double sets so a 1957 will have 2 of each coin with a face value of $3.64. This was done so both sides of each coin from each mint could be displayed in the cardboard holders that came with the set.
More than 300 million 1971 quarters were produced and any coin pulled from circulation has only face value.
