Cost/Benefit Analysis of Washers
Posted on November 22, 2007 - Filed Under Cool Ideas
This post is courtesy of an email that Hamid sent me. Apparently Tom Parker, author of Rules of Thumb, created a washer out of a penny instead of spending a lot of pennies to buy a washer.
Very cool idea. I also heard a rumour that the value of a penny is less than the cost of materials/manufacturing. I don’t know if this is true, but if it is, it probably explains some of the cost discrepancy. That and the natural abundance of pennies.
