A group of tourists learn about a "Blanket Toss"... by helping pull the blanket. This group was particularly strong! They managed to get virtually everyone who jumped all the way to the ceiling (which sometimes takes a lot of effort at teaching by the tour guides, but this group put the first one all the way up within 2 or 3 trys).

(Taken September 14, 2005 with a Nikon D1 digital camera at 1/40 second exposure, F3.2, using programmed auto exposure, using a Nikon 20mm 2.8 AF lens Nikon 80-200mm 2.8 AF-D lens set to 80mm.)
