There is way more pressure on the palm of your hand (underside of the wing) than on the back of your hand.
Yup. That's what everyone's saying too.
All those amazing scientific calculations (really, they are amazing how indepth they are), and nobody did the simplest of experiments.
Well done Mike. You will revolutionise aerodynamics with your simple experiment which
nobody in the course of airfoil history has
ever thought to try. Not NASA, not British Aerospace, not Skunkworks. All these stupid aerospace engineers making their fancy-dancy real working aircraft. What do they know?
