This causes a "burning" sensation similar to frostbite, and participants vie to withstand the pain for the longest time. The challenge can be recorded and posted on YouTube or other forms of social media. [2] The ice and salt create an eutectic frigorific mixture which can get as cold as −18 °C (0 °F). [3]
