Urchatz- (Washing of the hands) According to the Jewish law we are obligated to wash our hands before we partake in the Karpas or dipping the vegetables in salt water. We do not say a blessing at this point in the service while washing our hands.

Urchatz ― "Why do we wash our hands at this point in this Seder?" the Talmud asks. "Because it is an unusual activity which prompts the children to ask questions." The very name Haggadah means "telling," for the goal of the Seder is to arouse curious questions, and provide satisfying answers. (aish.com)

Eric’s tradition- instead of getting up and washing hands one person comes around with a bowl and water to wash hands
