- If you are really interested in testing this solution, why not
- just get some superglue and glue a bunch of coins together in a
- stack. Superglue forms very thin, rigid layers of adhesive so I
- wouldn't think that this would affect the outcome
- significantly. The trick here is to find coins of the right
- ratio, so that a stack of n coins will be the proper thickness.
