The foil is one terminal, and the water/metal object combination is the other. Do not allow the water or the metal object to touch the foil or spill over the side. This will short the capacitor and make it impossible to charge. Later you can use a voltmeter to verify if the capacitor can hold a charge.

What capacitors are used for are shown below: 1) RC Timing Circuit. A capacitor, when combined with a resistor, is used to form a RC circuit, which acts as a timing mechanism.
Capacitors also take a little time to charge, and you can change the amount of time by adding resistors and changing the capacitor size, so you can use capacitors to make delay elements too. You can make circuits that charge and then discharge, and the resultant waveform looks like an ugly sine wave.
