This weekend: ice skating with a waterfront view, explosive art and Swedish Holiday Bazaar What a view: The new Washington Harbour ice rink in Georgetown celebrates its grand opening on Saturday. Make it a day by popping into the Swedish Holiday Bazaar at the nearby House of Sweden. (Katherine Frey/The Washington Post) This weekend brings the first big sleighful of holiday-themed fun to Washington, including a celebration at a new ice rink, lighted boats, hand-crafted ornaments and a Christmas tree-lighting ceremony that will blow you away. The latter is one of Chinese Artist Cai Guo-Qiang's "Explosion Events" - a tree in front of the Freer Gallery of Art rigged up with 2,000 fireworks that will create an ethereal specter of a tree made out of smoke. The artist himself will set off the booms on Friday afternoon, giving you a fine reason to dip out of work early. Also among the highlights is Winter on the Water, a celebration at the 11,000-square-foot ice rink on the Georgetown Waterfront, which opened earlier this month. The event will feature a menagerie of entertainers, including ice skaters, choral singers, a St. Lucia Day parade, and food and beverages served outdoors by waterfront restaurants. To make a day of it, get there a few hours early Saturday and hit the nearby House of Sweden for the Swedish Holiday Bazaar, one of our favorite holiday markets of the season (credit the Swedish cafe for serving strong coffee and Swedish pastries).
