Quarter Shrinker
The Quarter Shrinker was constructed by Rob Flickenger at Hackerbot Labs.
Quarter Shrinking has three steps.
1. make a coil of wire,
2. stick quarter inside it,
3. discharge an enormous amount of electric current through the coil.
But what does that actually do, other than making a big boom? … (click for more)
Passing current through a coil of wire produces a magnetic field. In this case, with so much current, the magnetic field produced is gigantic: the coil becomes a magnificently powerful electromagnet.
The creation of a magnetic field in the coil-now-magnet induces a circling current to flow around the coin sitting inside the coil. This current in the coin also produces a magnetic field (i.e., the coin becomes another electromagnet). The kicker is that the coin’s magnetic field and the coil’s magnetic field point in opposite directions, so the coin and the coil repel each other furiously.
This repulsion creates forces which overcome the strength of the metal; the coil is expanded out and explodes, and the coin is pushed in and shrunk.
Before and after.
The quarter shrinker itself and the trigger setup. The yellow box sits around the coil through which the voltage is discharged to protect bystanders from shrapnel.

So what are you using to treat your Asperger’s Syndrome?
The coin retains its density,the diameter of the coin is reduced while at the same time its thickness increased.

This ABUSE of coinage will NOT be TOLERATED!
@Ivan Smith
LOL!The mass of the coin stays the same!the diameter is reduced while the thickness increased.
Presumably, the mass isn’t changing. So, is the quarter becoming thicker, or is it more dense? It would be interesting to see a side-by-side picture of the quarters’ edge.
i understand that there is a lot of electromagnetic engineering involved with this quarter shrinking device. what i don’t get is what the point of all this is?
do these guys really go around town talking incessantly and endlessly about how they use batteries and magnets to blow up a quarter?
they’re spending money on destroying money, so in that sense IT IS AWESOME! but so pointless.
A similar device was built in the electrical and computer systems engineering department’s Plasma Dynamic Lab at RPI some years ago. It was primarily used for turning aluminum cans into smoldering balls. For added amusement, the device could be loaded with something like a banana wrapped in aluminum foil.

I hope that soon everyone associated with Intellectual Ventures Lab, from Nathan Myhrvold to friends such as Hackerbot, will have read Dr. Robert O. Becker’s book The Body Electric.
Here is a cautionary tip-of-the-iceberg glimpse from a review on Amazon, I don’t have time now to find a review that is worthy of the book > but what is significant about Becker’s work is not the special effects but what he discovered about basic life science by literally taking life in his hands.
“By Faith Dyson (Oklahoma) – See all my reviews
This review is from: The Body Electric: Electromagnetism and the Foundation of Life (Paperback)
Let’s keep this simple. Robert O. Becker discovered that Metabolism, our “Biological Clock AND Compass”, is disoriented by the plethora of electromagnetic pollution spewed out by our government and corporate facilities, ( ie: everything from Radar Beams, Microwaves, radio waves and Cell Phone frequencies ), which discovery smacked Western Civilization/Technology, ( not just that of the U.S., but of other countries as well ), in the face.
What does this metabolic “Disorientation” cause, or rather, prevent? It inhibits our perfect DNA replication/mitosis. This means that the multiplication and division of the information necessary to create correct cell replication is prohibited in the Global Population subjected to such abnormal, multi-level electromagnetic frequencies… and the very entities making money off of our denied replication, ( read that as Health! ), are making money “hand over fist” from the misery they are causing in us.
Whether he realized it or not, Becker gives us “THE” cure for all genetic/cellular/chemical, ( ie: Endoderm, Mesoderm, Ectoderm/Neurological, Endocrinological, Immunological, Genetic, and Atomic ), dysfunction on page 249 of his book. It is our return to normal bio-rhythm/metabolism within the “infinitesimal field ( 0.025 volts per centimeter ) pulsing at 10 hertz”, which also just so happens to be the Earth’s natural frequency – and the tempo of Mozart’s music. ( See also “The Mozart Effect” by Don Campbell. ) “

There is something interesting I think is occurring during the quarter shrinking phenomenon that is not specified in the explanation above. Namely, the chronology of the event. Once the quarter inside the coil becomes an electro magnet itself and they begin to repel one another vigorously, the weakest link in the relevant system of forces attempting to stabilize one another is the quarter’s intramolecular structure, producing the shrinking. This is what I’m saying: after this occurs to a certain degree (i.e. the quarter shrinks down to the size we ultimately see after the event) the force required to continue to shrink it into a smaller size is greater than the force it would take to just blow the whole thing sky high (expand the coil).
This is an interesting phenomenon for many reasons and some of them may have some very powerful practical use. Scientifically, I’m curious to know what would happen if the coil structure was made of a stronger material – would it demand that the quarter shrink further down before the coil itself is overcome? Can the coil be made so that it does not fail? And if so, what happens then? Does the quarter shrink down into the the shape filling in the space in the center of the magnetic fields surrounding it, the points of where there is the least magnetic force? There are many questions.
In the practical sense, this technology can develop into a way we craft a magnetically influenced prone object. With advanced knowledge and tools, we could deduce a method by which to manufacture an item by enveloping it in a magnetic field – shaping it into the form we wish it to be.
We gotta start somewhere joe m.
Сдесь комменты можно почитать и в цирк не ходить!! бред какойто.
Shrinking a Quarter?
I think about all the worlds future energy issues and if any one of those “Brains” put some real effort into solving problems instead of playing “Honey I shrunk the Quarter!” They might try looking for a better way to turn those High Voltage Capacitors into better batteries! A new “Capacitor/Battery system” that would charge instantly but drain slowly over time instead of this huge burst of violent energy trying to shrink quarters! Grow up gentlemen, there are bigger issues you need to be focusing on other then wasting huge amounts of energy playing with small change! In “my view” this is a total waste of time, money and brain power!
