Connect the capacitor to one of the HP power supplies located in L35. Charge the capacitor to 100-140 V (the more V the louder the bang).After the capacitor is fully charged, disconnect it from the power supply(or, if using a switch to charge up capacitor, flip switch to “discharge”).Finally, short the capacitor leads with the metal part of the screw driver. A loud bang and bright spark will imediately ensue.
