Netanyahu and Stewart each sent a text message from the cellphones selecting the Dead Sea as one of the New7Wonders of Nature, when the prime minister's wife turned to the American guest and informed her that her younger son, Avner Netanyahu, was responsible for the idea of promoting the Dead Sea through text messages.
"Do you know who came up with this idea first, before the whole country became involved? Our son. It was about a year ago. When he was 14 or 15 he noted that the Dead Sea had potential and said, 'Dad, you must do something about it.'"

Martha Stewart landed in Israel on Thursday on an El Al flight. She arrived for a six-day visit, to attend the wedding of the daughter of Israel Museum Director James Snyder and to tour the country.
Stewart, 70, is a media personality with a business empire marketing a variety of home-improvement products and the publisher of cook books and lifestyle magazines.
Before heading to the Holy Land, Stewart tweeted about the preparations for her trip, posting a picture in which she is seen holding the map of Israel. "Despite the hurricane, a life must go on. Planning a wonderful trip to Israel!" she wrote.
She also said that her nephew, musician Chris Herbert, was travelling with her. "He speaks fluent Arabic and a bit less fluent Hebrew - great for me!"
