I was surfing this morning before I left for the airport, and came across this site. Mich started stacking pennies together, and the results are amazing! It is…
…a collection of pictures from a talk I gave while a Civil Engineer at Texas Tech University in 1980. Our senior year we practiced giving technical presentations. This was mine.
All stacks of pennies were done without any glue. Only the weight of the pennies provides the support.
