The Ice Bucket Challenge, sometimes called the ALS Ice Bucket Challenge, is an activity involving dumping a bucket of ice water on someone’s head to promote awareness of the disease amyotrophic lateral sclerosis (ALS) and encourage donations to research.
The challenge dares nominated participants to be filmed having a bucket of ice water poured on their heads and then nominating others to do the same. A common stipulation is that nominated participants have 24 hours to comply or forfeit by way of a charitable financial donation.
Eunji of A Pink nominated Seungyoon for the challenge. Seungyoon & Eunji are both from Busan and attended the same music class.
