The legs of a 100Ω resistor are bent to the right fit for the capacitor contacts and held in the teeth of a pair of pliers for a few seconds. You can use the highest setting of your voltmeter to check that the capacitor has discharged to a safe level (say, 50V). If you have a high-wattage resistor, all the better. If it is not high enough power, it will break, but not in as spectacular a way as a capacitor being discharged dangerously.

Some devices that can pack a painful and sometimes lethal punch are:

● Old glass CRT TVs ● Switch-mode power supplies ● Camera flash guns and disposable cameras with a flash
