The Ice Bucket involves a person pouring a bucket of ice water over his or her own head and challenging three others to do the same or donate to fight ALS. The ice water symbolize the effect of being "frozen", or paralyzed. Since it started, celebrities around the world have participated in the challenge.
It was also the same date when Park Shin Hye's agency 'S.A.L.T. Entertainment' uploaded a video in YouTube about our Princess participation in the same challenge.
