Facebook CEO Mark Zuckerberg has filmed himself taking part in the 'Ice Bucket Challenge' in order to raise money and awareness for ALS.
The 30-year-old poured a bucket of ice water over himself and then nominated three people to follow suit and take part in the challenge; his Facebook partner Sheryl Sandberg, Bill Gates and Netflix CEO Reed Hastings.
The nominees have 24 hours to complete the challenge or they have to donate $100 (€75) to ALS foundation. Although we are pretty sure these millionaires will be happy to donate to the cause either way.
ALS, amyotrophic lateral sclerosis, is a devastating neurodegenerative disease that sees a rapidly increasing muscle spasticity, difficulty speaking, weakness due to muscle atrophy and difficulty breathing and swallowing.
