[Avodah] Tamim Tihyeh

[Moshe Y. Gluck]

Someone on Areivim wrote about a practice called "Blei Gissin." Apparently,
the practitioner pours molten lead into a bucket of water, and based on the
shapes that come out, both exorcises Ayin Hara and predicts the future. The
Ayin Hara part I can't think of a problem with, except possibly Gezeilah.
Isn't the predicting future part Assur, though, because of Tamim Tihyeh?
(According to the article linked on Areivim (http://tinyurl.com/2v3fsk):
"The storm is about to stop and soon the lights will go on.")
