lupLupita Nyong’o’s brother Peter Nyong’o has joined the long list of celebrities taking the Ice Bucket Challenge.

Basically, a person records a video of himself/herself pouring ice cold water on himself/herself. This is after being challenged by someone else. Failure to accept the challenge means you should automatically donate $100 to an Amyotrophic lateral sclerosis (ALS) related charity.

Among the celebs who have posted videos of themselves doing the stunt include: Justin Timberlake, Taylor Swift, Mark Zuckerberg, Bill Gates, Cristiano Ronaldo, Justin Bieber etc.

Peter Nyong’o posted his video on instagram. Here it is.
