Salt and ice challenge

[1] This causes a "burning" sensation similar to frostbite, and participants vie to withstand the pain for the longest time.

The ions in sodium chloride (table salt) are heavily influenced by the molecular polarizability of the ice.

The melting point of ice is decreased due to the incorporation of table salt and this then causes a binding of the two substances.

[8] The stunt leaves behind an ice burn that increases in severity the longer the chemical reaction on the skin continues.

[9]  The freezing of tissue between the dermal and epidermal levels of the skin leads to a disruption in blood circulation, initially causing frost nip.

[10] After a few days, depending on the severity and duration of the burn, epithelial cells should slowly regenerate along with scarring and surface disruption.
