At the conclusion of the blessings, after the couple drinks from the second cup, the groom breaks the glass (anything from actual glass cup to light bulb) wrapped in a cloth with his right foot. The symbolism of the smashing of the glass by the groom at the conclusion of the ceremony has a variety of explanations.

One is that the shattering ushers in the outbreak of merriment that should immediately follow the pronouncement. Guests usually respond with "Mazal Tov!" ("Congratulations!").

Another explanation is that the breaking recalls the destruction of the temple in Jerusalem. Even at height of personal joy, sadness is remembered. The verse, "If I forget thee O’ Jerusalem, let my right hand forget its cunning: If I do not raise thee over my own joy, let my tongue cleave to the roof of my mouth", is sometimes recited at this point.

The breaking also reminds us of the fragility of personal relationships. The glass is shattered with the implication that the marriage should always remain intact.

Finally, the breaking of the glass is sometimes explained as symbolic of the breaking of the bride's hymen. In Jewish marriage, sexual union is expected and required. Today, some couples chose to break the glass together.
