pThis past Halloween, Aviram Carmeli dressed up as Harry Potter and glided across Westminster Bridge in London to catch a snitch that flew in front of him.ppThe idea was created by Aviram Carmeli, Ishay Lewkowicz and Aviad Rosenfeld who build a costume every year on the Jewish holiday Purim. Every year, they create a costume and, in the past, they have created an Alladin costumea and a Titanic costumea.
