Measuring three metres tall and two metres wide, this enormous bag was declared the world's largest backpack by the Guinness World Records officials in October 2009.

Hisham Zuhir, director at the sack's makers Rainbow Max, said: "Our determination to help children in education inspired us to create the worldÂ’s largest backpack, and for the world record to be held in a world famous city, as it was truly a combined effort between various teams in Hong Kong and other countries. We want to prove that hard work and innovation can help girls reach inspiring heights."
