Oversensitive 555 monostable multivibrator

Ok, firstly I was daft enough to think I could jump back into electronics after 10 years! :( <p>I have the circuit mentioned above, it's being used on a "buzzing wire" game to make a long buzz every time the wire is touched.<p>The trigger (pin 2) is held high by way of a 100pF capacitor, the voltage...
