How can i measure lift of a model airfoil without a windtunnel? - lift and carrytorrent

I have to go a project for the science fair, and I wanted to do with the aerodynamics. I wondered how I created the amount of lift of the model of the wings of styrofoam, could be measured without the blower. Is it possible to create a balance beam and the poor only a connection to him. The create with a fan so that airflow and add weight to see how you can trigger the sails. I really need to made quickly. THnkazz: O
