Isn't it better to use a Darlington transistor?Much of the comments above I recognize as the circuit is not sensitive enough to detect the human body's resistance...Darlingtons may solve that. An alternative is to use the transistor twice where the first emitter is directly connected to the second base and both collectors are connected to the +. (a.k.a. poor man's Darlington).
