You may have seen shrunk coins before but you may not have seen the technology that goes behind making them. Thanks to Aud1073cH for sending in the video above that The Geek Group made showing how they make the coins that they sell as a fund raiser item. If you are interested in purchasing other coins such as the Canadian Toonie (pictured below) have a look at this site here.
“After many months of designing, engineering, prototype-building and planning, we are finally shrinking quarters with Project Stomper! The quarters are shrunk with impressive power behind them: 6,000 volts and 100,000 amperes. After the process- which happens in less than 1/100th of a second – the quarters are now about the width of a dime, although significantly thicker.”
