The popular MBC entertainment program "Infinite Challenge" member Jung Joon Ha learned about the relationship between ice and salt tad bit later than he should have.

On the most recent episode of the MBC entertainment programs "Infinite Challenge," which aired on August 9, 2014, the Infinite Challenge members Noh Hong Chul, Ha Ha, Park Myung Soo, Yoo Jae Suk, Jung Joon Ha, and Jung Hyung Don challenged themselves to protect their blocks of ice from melting in hot, humid weather. They borrowed blocks of ice from the ice protector Kim Hak Chul for a mission, where they had to protect their blocks of ice from melting until a given time. Jung Joon Ha, while walking alone said, "I need salt. Salt makes ice melt less." However, after walking with his block of ice covered in salt for a few minutes, he realized that salt actually melts ice and said, "Does salt melt ice?" and made people laugh. In related news, on the most recent episode of the MBC entertainment program "Infinite Challenge," Infinite Challenge members played a survival game protecting their own block of ice from melting in hot, humid weather.
