Put 100 coins on the table.    Make the widest structure that you can that stands at least 1 inch tall with the coins.  Every coin must touch another coin and try to have the fewest coins touching the table.   Measure the width and send your results to me at nancyfootehigley@gmail.com.

When you’re done, check out this.
