Uncirculated Delaware Quarter Shrunk by Ultra-strong Magnetic Fields! This is a genuine uncirculated Delaware state quarter that has been electromagnetically "shrunk" by extremely powerful magnetic fields. Using specialized equipment in my high voltage lab, I created invisible, but very intense, pulsed magnetic fields which "hammered" the outer rim of the coin inwards, evenly shrinking it to the diameter of a dime. The whole process only took 20-25 millionths of a second, and was accompanied by an explosion and a blinding blue-white flash! Technical details will be provided in a one-page summary supplied with the coin. Shrunken coins are an amazing demonstration of the incredible power of ultrastrong magnetic fields. This is NOT magic or "Honey, I shrunk the kids" science fiction, it's high-power electromagnetism at work. Each coin requires its own hand-wound coil which is explosively destroyed during the shrinking process. A shrunken coin weighs the same as before - it's simply smaller in diameter and a bit thicker!  Also, please check out our other auctions. Amazingly, the coin's features remain beautifully preserved through the shrinking process! Each coin comes with a one-page explanation of the how the shrinking process works.  NOTE: Send me an eBay message to substitute a different state or Eagle quarter. Shrunken coins are educational and unique - and they are only available from Stoneridge Engineering. Physics CAN be fun! A unique gift for the collector or amateur scientist on your list!
