Magic
it works by spraying Dust-Off on a coin and then blowing on it. The preparation only lasts for about five mins and really not worth the effort. Hopes this helps
I don't do levitation
No, the noun 'coin' is a countnoun, the plural form is coins (one coin, six coins).
When a coin ages it lowers the mass of a coin because usually some of the metal such as copper on a penny comes off the coin leaving it with a lighter mass then it started off with.
Original coin slots used a system of weight and thickness tests to check to see if a coin was valid.In a vertical mechanical slot a coins initial size is tested by the slot guard which is a metal plate keyed to he vertical size of the coin. It then drops into a cradle which has a counter balance which tilts at a calculated speed dependant of the weight of the coin. After this it rolls down a guide which has a gap which is slightly smaller than the width of the coin passing a magnet on the way. The magnet will pick up iron based slugs but will also slow coins of other materials as well. Then the coin rolls off the end of the guide jumping a gap and hitting a nylon angle. The speed at which this impacts determines how far it bounces off the nylon into one of two slots. the closest slot is the reject return and the farthest the accept slot. If the coin is to light it won't bounce far enough to be accepted. Once the coin has been accepted it will pass by an anti-strimming latch which prevents the old coin on a string trick. Further to this some slots use dual micro-switches that time the decent of a coin and trip an alarm if the coin drop is too fast or slow. Finally the coin drops through a microswitch to register the coin to the CPU. There are various other designs of mechanical slot but the vertical type are the most frequently used.On a modern electronic slot this process is more simple and more complex at the same time. On these slots weight and size are irrelevant. what is important here is metal composition. Using the principle of back EMF effect a coin is passed down a slope at a known speed determined by its mass past a number of coils. The interaction of the coin and the coil creates a voltage which is read by a ADC and compared by a microprocessor to a set of known values stored in a ROM. If the coin does not produce the correct values a signal is sent by the microprocessor to open a section of the rail and drop the coin out of the reject slot. If the coin is accepted it continues down and past a pair of opto-sensors which look for strings, nylon strimmers etc. If the second opto is tripped and the drop time between the pair is right for that coin it will be registered as accepted.Needless to say that the electronic slot is very resistant to fraud since it not only tests the size & mass of the coin but also its metal composition as different metals produce different back EMF values. It also has the advantage of being able to accept any size or shape of coin made in any country through a quick ROM change.
MAGIC!
It's a magic or trick coin an has little or no value.
No. You have a trick coin available at magic shops.
A trick coin that you buy at a magic shop, I reckon.
Many ways. Eat it. Do a magic trick. Throw it. Drop it. Give it away.

your hand
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!
Is this a trick question, a 2p coin is too wide to pass through the neck of a 2 litre bottle, so the answer is none.

Some simple magic tricks for children include the disappearing coin trick, the magic coloring book trick, and the rope trick where a cut rope is magically restored. These tricks are easy to learn and require minimal preparation, making them perfect for kids to amaze their friends and family.
magic coin tricks are a sleight of hand, best way to learn is as an apprentice.
