First, I would like to share this timeless classic of Uri Geller being debunked by the Amazing Randi:
On page 182 of Chopin and Beyond, Byron Janis tells a story about the death mask of Chopin on his piano that began to weep salty tears in the presence (and at least one hand) of Uri Geller. I imagine that Geller might have used a gimmick, like a little cellulose bubble filled with salt water, to make this illusion.
Janis mentions that his Chopin death mask was "one of three originals in the world." I thought that Auguste Clésingerone made only two, along with a cast of Chopin's left hand. I think that Janis might have been "had" more than once.
