Ninety pupils from a primary school were given a behind-the-scenes tour of an Amazon fulfilment centre.

The children from Barrow Hall Primary School visited the 400,000 sq ft Warrington facility to see what happens when customers click 'buy' on an item.

They were shown how Amazon stores, picks, and packs products, and how customer orders are shipped from the site.

Christian Stewart, the general manager of Amazon in Warrington, said: "It was a pleasure to welcome the children of Barrow Hall Primary School to our site.

"It was great to see the pupils’ curiosity and answer their questions as we showed them what goes on behind the scenes at Amazon after people hit 'buy' on an item."

The visit left a lasting impression on the young visitors, with Hasan, a pupil from Barrow Hall Primary School, stating: "It was really cool to visit Amazon and see all the machines they use to package our stuff.

"I liked the robots the most."

"The children had a great time learning about how Amazon works, and the team was very friendly, encouraging the kids to ask questions as we went along.

"Experiences like this, outside of the classroom, are crucial for introducing children to new learning environments to foster their imaginations, and we are grateful to have had this opportunity."

The tour is part of Amazon's community engagement initiatives.

Amazon co-founded the Multibank initiative with former UK Prime Minister Gordon Brown to support families in need.

The Multibank network has donated more than three million surplus goods to over 400,000 families across Greater Manchester, Scotland, Wales, and London.

Amazon has also supported more than 700,000 students across the UK with free STEM education programmes through Amazon Future Engineer.
