Water itself can be electrolysed, but only to a small extent. To tap water, I've added some household table salt to act as a initiator and to speed up the electrolysis process of water.

The cathode here is the top one. It effervesced more than what you see at the anode. The gas given off is hydrogen , at the cathode, while oxygen is given off at the anode.

It takes 2 moles of Hydrogen is given off while only 1 mole oxygen is out. Hence there are fewer O2 bubbles.
