This is a fun one.  It's a 3x5 note made into a sort of hovercraft glider.  Previously, I had been blowing underneath the glider, thinking that would push it across the table.  I finally discovered that you should blow into the curved part at the front.  This is your classic rear-wheel drive scenario.  If the power comes from the back, there is a tendancy to for the rear to get ahead of the front.  If the power comes from the front, it will pull the rear along with it.  It's all physics that I barely understand.
