Eagle Style Washington Quarter Shrunk by Ultra-strong Magnetic Fields! This is a genuine US quarter that has been "shrunk" by extremely powerful magnetic fields. Using specialized equipment in my high voltage lab, I created invisible, but extremely 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 millionths of a second, and was accompanied by an explosion and a blinding blue-white flash! Technical details are included 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 my 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. Actual year and mint mark may vary from the example pictured below.  NOTE: Send me an eBay message if you'd like to substitute a state quarter. Shrunken coins are educational, unique, and they make ideal gifts. Physics CAN be fun! A unique prize for that collector or amateur scientist on your gift list!
