From texting and selfies to Facebook and Twitter, parents of teenagers will know how hard it can be to get them off their mobile phones.
Students at Billerica Memorial High School in Massachusetts in the U.S. have done something amazing for their classmate, Ian Cadden, who is sufffering from luekemia.
Not only did they make the 12 year-old honourary captain of the hockey team, but they are also "Celling Out for Leukemia", meaning they have decided to give up their mobile phones for a month to raise money for leukemia.
From April 17th until May 16th, 101 mobile phones will be kept in the police station in Billerica.
Glenn Corbett, a dad of one of the players, spoke about his admiration for the students saying: "Any high school-aged kid who is willing to give up their cell phone for a cause like this is incredible to me."
The Billerica community have been raising much needed funds by sponsoring the teenagers to give up their phones.
It has also been reported that the students could find their efforts on the pages of The Guinness Book of Records.
