Maybe a free online demonstration would help? I'd suggest a rebuttal of molecular determinism through quantum and/or chaos theory. There's still people around who state that if they could feed the velocities and trajectories of all my particles in some great computer, they could predict what I was going to say next.
("Platypus contingency fillets yellow wherewithal" "I knew you were going to say that!" - you know the kind.)
Give some good arguments against determinism and I'll start referring folk to you. (You also tutor online, I presume?)
