Was it a kind of new，cool way to deal with the summer heat？Of course not．It's a game to increase awareness of the illness ALS and encourage donations（捐贈(zèng)） to research．
Last summer，the challenge first spread rapidly across social media and late-night talk shows in the US．And soon，it was popular around the world．
The challenge way is easy．It needs the persons who receive the challenge to pour a bucket of ice water over their head within 24hours，or donate money to help fight ALS．Even if a persons completes the challenge，he or she is welcome to donate money，too．
Once a person completes the challenge，he or she is supposed to give the same challenge to several other people，usually three，which is why the number of people that took the challenge grew so quickly．
