Not ice but still abuse
There is an unconfirmed rumor that the "ice" in the vat is actually stage ice, which would not lower the temperature of the water. Nonetheless, these are heavy terrestrial snakes which are at grave risk of pneumonia and drowning, as well as injury from the contestants. Furthermore, people watching this may easily assume that it is safe to treat pet snakes in this way, since PETA has declared that the snakes are not at risk in this show. This is simply unacceptable.
