Set the egg carton separators flush against the furnace pipe, at the end opposite the window. Set the electric fan inside the box containing the egg carton separators. These separators "honeycomb" or straighten the swirling air currents from the electric fan.
When you suspend your glider in the wind tunnel you can examine the aerodynamic effects of control surfaces (ailerons, elevator, and rudders) and different glider designs. Also examine what happens when you change the airspeed, or add weights (pennies are good) to different positions on your glider, or change your glider's design.
