Friday February 25, 2011, Fifth Day - ANSWER!

Todays problem is:

A giant inverted steel pyramid is perfectly balanced on its point. Any movement of the pyramid will cause it to topple over. Underneath the point of the pyramid is a $100 bill. How could you remove the bill without disturbing the pyramid?

(Baker-Sennett & Ceci, 1996; Jacobs & Dominowski, 1981; Schooler & Melcher, 1995). 

Tear, cut, or burn the bill.
