Both the United States and Canada have teamed-up to color the immense Niagara Falls green for Saint Patrick’s Day. And for those wondering just how much green food dye that will actually take? Well none, as a matter of fact. Much like the London Eye, the Empire State Building, and the Pyramids in Egypt, the Niagara Falls Illumination Board will use an intricate light display on the falls. Two 15-minute long illuminations will take place at 9 p.m. and 9:30 p.m., EST.
