#1102: ChangeChain

Loose change is generally a nuisance -especially the brown shrapnel kind.

Today’s invention is to create coins which each contain a bar magnet. This would allow all coins automatically to align themselves into a convenient column within someone’s pocket. No more rattling during presentations and, when you need to spend some change, just flip the required coins off the top of the stack.


If you wanted to go one step further, you could have slightly dished coins so that these could be arranged, partly overlapping each other, in the form of a bracelet or necklace.


  1. Yes that would be great! It is a nuisance to dig through my bag looking for all the coins scattered inside… it would be terrific if they could all stick together. Wonder if there’s any magnetic paint or coating we could use for coins that have already been produced?

  2. Hi Jessica,
    Ideally we can soon do away with that medieval stuff anyway, paying for everything, even small items, by iris recognition, or something. The coolest thing I’ve seen recently is programmable magnets: http://www.popularmechanics.com/technology/industry/4337757.html
