It may not be a usual classroom activity but students went popping mad for this bizarre challenge.
A total of 366 students at Hawthorne High School, New Jersey, set a new world record for the most people popping bubble wrap at one time.
The students crammed into the school's gymnasium to jump on 743sqm of bubble wrap for two minutes, earning them official recognition from Guinness World Records.
The school has a special affinity with the addictive material - bubble wrap was invented in Hawthorne in 1960, by Marc Chavannes and Al Fielding.
As well as entering in the record books, the school raised money for the Sandy Hook Elementary School Fund in Connecticut, which supports people affected by the shooting which saw 20 schoolchildren and six teachers killed in December last year.
